Description
본 발명은 중금속 흡착용 3중 필터 및 이를 포함하는 수질 정화 장치에 관한 것이다. 보다 상세하게는 중금속 및 유기물 흡착이 가능한 친환경 재료를 사용하여, 환경오염을 저감 시키는 효과가 있으며, 친환경적으로 우수한 중금속 흡착 및 폐수를 정화가 가능한 중금속 흡착용 3중 필터 및 이를 포함하는 수질 정화 장치에 관한 것이다.The present invention relates to a triple filter for adsorbing heavy metals and a water purification device including the same. More specifically, the present invention relates to a three-layer filter for adsorbing heavy metals capable of adsorbing heavy metals and purifying wastewater, which has an effect of reducing environmental pollution by using eco-friendly materials capable of adsorbing heavy metals and organic matter, and a water purification device including the same.
경제성장과 더불어 지속되는 산업화와 도시화로 환경오염은 날로 심각해지고 있으며, 완전히 처리되지 않은 하 폐수 중의 수질오염물질이 하천이나 호소(湖沼)를 비롯한 기타 상수원에 유입됨에 따라 효율적인 수질관리에 많은 문제점을 발생시키고 있다.Environmental pollution is becoming more serious day by day due to continued industrialization and urbanization along with economic growth, and water pollutants in sewage that have not been completely treated are introduced into rivers, lakes, and other water sources, causing many problems in efficient water quality management.
이의 처리를 위한 시설 역시 고도화되고 처리비용도 증가되고 있는 실정이며, 우리나라는 단기간에 걸친 산업발달로 일반하수, 산업폐수, 각종 폐기물의 매립 및 농약살포 등을 통해 다양한 오염물질이 하천 및 강으로 배출되고 있는 만큼 수질 환경뿐만 아니라 인체 건강까지도 위협받고 있는 실정이다.Facilities for its treatment are also being advanced and treatment costs are increasing. In Korea, various pollutants are discharged into rivers and rivers through general sewage, industrial wastewater, landfill of various wastes, and pesticide spraying due to industrial development over a short period of time. As a result, not only the water quality environment but also human health is threatened.
특히, 중금속의 수요량은 하루가 다르게 증가하고 있다. 이들 대부분은 유독성으로 인해 인체 및 생태계에 광범위하게 영향을 미칠 뿐만 아니라 하천 및 토양 등의 환경에 심각한 오염원으로 작용하고 있다. 중금속의 주요 배출원으로는 산업폐수, 도시하수, 농약 살포 등이 있으며, 산업체 중에서는 도금 공장이나 제련, 피혁, 안료 및 제약 업체 등에서 카드뮴, 아연, 구리, 니켈, 납, 수은, 크롬 등 생물체에 유해한 중금속을 과량 배출하는 것으로 알려져 있다. In particular, the demand for heavy metals is increasing day by day. Most of these not only have a wide range of effects on the human body and the ecosystem due to their toxicity, but also act as a serious pollutant to the environment, such as rivers and soil. Major sources of heavy metals include industrial wastewater, urban sewage, pesticide spraying, etc. Among industries, it is known that plating factories, smelting, leather, pigment and pharmaceutical companies emit excessive amounts of heavy metals harmful to organisms such as cadmium, zinc, copper, nickel, lead, mercury, and chromium.
무분별한 중금속 배출에 의한 수질 오염은 지난 수십 년간 전세계적인 문제를 야기해왔다. 인간과 생태계에 특히 악영향을 미치는 독성 금속 원소로는 비소(As), 크롬(Cr), 구리(Cu), 납(Pb), 수은(Hg), 망간(Mn), 카드뮴(Cd), 니켈(Ni) 등이 있다.Water pollution by indiscriminate discharge of heavy metals has been a worldwide problem for the past decades. Toxic metal elements that have particularly adverse effects on humans and ecosystems include arsenic (As), chromium (Cr), copper (Cu), lead (Pb), mercury (Hg), manganese (Mn), cadmium (Cd), and nickel (Ni).
상기와 같은 중금속은 다른 물질에 비해 생물에 대한 자체 독성이 높고 인간 접촉 가능한 환경매체 내에서의 잔류기간이 길며, 독성 유기화합물과 달리 생물 분해성이 없으므로 생물체 내에 축적되어 다양한 질병과 장해를 유발하는 것으로 알려져 있다. Heavy metals as described above have high self-toxicity to organisms compared to other substances, have a long residence period in an environmental medium that can be contacted by humans, and are not biodegradable unlike toxic organic compounds, so they accumulate in organisms and cause various diseases and disorders.
따라서, 종래에는 하천수, 지하수 및 폐수에 존재하는 중금속의 제거를 위해, 화학적 침전법, 이온교환 수지 및 분리막을 이용한 제거 법 등이 제시되었다. 그러나 화학적 침전법을 이용하는 경우에는 중금속 제거 처리 후에 발생하는 많은 양의 슬러지가 2차 오염물질로 작용하고, 저농도의 중금속을 완전히 제거하지 못하는 문제점이 있고, 이온교환 수지나 분리막을 이용한 제거법은 고형의 오염물질을 다량 함유하는 오염수의 처리가 어려우며, 비용이 많이 드는 문제점이 있다.Therefore, conventionally, for the removal of heavy metals present in river water, ground water, and wastewater, a chemical precipitation method, a removal method using an ion exchange resin and a separation membrane, and the like have been suggested. However, in the case of using the chemical precipitation method, a large amount of sludge generated after heavy metal removal treatment acts as a secondary contaminant, and there is a problem in that low concentration heavy metals cannot be completely removed. It is difficult to treat contaminated water containing a large amount of pollutants, and there is a problem in that cost is high.
중금속을 처리하는 많은 알려진 기술 중에서 흡착은 비용 효율적이고 단순한 작용에 의해 이루어지는 바, 최근에 대두되고 기술분야이다. 하지만, 종래 기술에 따른 중금속 흡착제는 여전히 낮은 흡착용량으로 중금속 흡착에 비효율적인 바, 높은 흡착용량을 구비하여 중금속을 효과적으로 제거할 수 있는 흡착제의 개발이 요청되고 있다.Among the many known technologies for treating heavy metals, adsorption is a cost-effective and simple operation, which has recently emerged and is a technical field. However, since the heavy metal adsorbent according to the prior art is still inefficient for heavy metal adsorption with a low adsorption capacity, there is a need to develop an adsorbent having a high adsorption capacity and capable of effectively removing heavy metals.
최근에는 수산화 마그네슘과 같은 금속산화물은 중금속 흡착에 탁월한 효과를 발휘하는 것으로 알려진 바, 중금속 처리에 있어서 비표면적을 높여 흡착용량을 증대시킬 수 있는 꽃 형상의 나노 사이즈 금속산화물이 대두되고 있으나, 파우더 형태의 나노 사이즈의 금속산화물은 유체로부터 용이하게 분리될 수 없는 문제점이 있고, 또한 낮은 수리전도도 및 높은 압력강하 때문에 컬럼 모드에서의 중금속 처리에는 응용될 수 없는 현실적인 문제점을 안고 있다.Recently, metal oxides such as magnesium hydroxide are known to exert an excellent effect on adsorption of heavy metals. Flower-shaped nano-sized metal oxides, which can increase the adsorption capacity by increasing the specific surface area in heavy metal treatment, have emerged. However, nano-sized metal oxides in powder form cannot be easily separated from fluids, and also have practical problems that cannot be applied to heavy metal treatment in column mode due to low hydraulic conductivity and high pressure drop.
이에 종래 인체에 유해한 중금속으로 인한 피해를 줄이기 위한 많은 연구가 진행되고 있다. 이러한 문제를 해결하기 위해 전극 이온 교환법 등의 다양한 공법이 개발되고 있으나, 유입량이 크고 수중에 있는 Fe, Cd 등의 성분이 고농도일 경우 과대한 설치비용과 유지관리 비용으로 인해 널리 활용하는데 어려움이 많으며, 또한 별도의 관리 인원이 필요하다는 문제점이 있다.Accordingly, many studies have been conducted to reduce damage caused by heavy metals that are harmful to the human body. In order to solve this problem, various methods such as electrode ion exchange are being developed, but when the inflow is large and the components such as Fe and Cd in the water are high in concentration, it is difficult to widely use due to excessive installation and maintenance costs, and there is also a problem that separate management personnel are required.
또한, 현재 상용되는 중금속 수질 정화법은 일반적으로 미생물을 이용한 방법, 식물을 이용하는 방법, 화학약품을 이용한 방법, 흡착제를 이용하는 방법 등이 있다. 그러나, 미생물을 이용한 방법은 처리 시간이 많이 소요되고, 미생물이 하천에 방류되면 2차 오염을 야기할 수 있으며, 화학 약품을 이용한 방법은 화학 약품의 가격이 비싸고, 처리 과정 중 필요한 적정량을 산정하기 어렵다. 이에 반해, 흡착제를 이용한 방법은 경제적이고, 무독성으로, 보다 효율적인 수질 정화방법을 찾기 위한 연구가 진행되고 있다.In addition, currently commercially available heavy metal water quality purification methods generally include a method using microorganisms, a method using plants, a method using chemicals, and a method using adsorbents. However, the method using microorganisms requires a lot of treatment time, and when the microorganisms are released into the river, it may cause secondary contamination. The method using chemicals is expensive, and it is difficult to calculate the appropriate amount required during the treatment process. On the other hand, the method using an adsorbent is being studied to find an economical, non-toxic, and more efficient water purification method.

상기 본 발명의 고분자 형태의 섬유재는 중금속 흡착용 필터 소재로 오염수의 부하를 낮추기 위해 부직포 형태의 섬유재를 포함하며, 유입수가 통과할 수 있도록 기공 크기는 대략 0.01um 내지 1um 구성되는 것이 바람직하다.The polymeric fibrous material of the present invention is a filter material for adsorbing heavy metals and includes a nonwoven fabric type fibrous material to lower the load of contaminated water, and preferably has a pore size of about 0.01 um to 1 um so that influent water can pass.
본 발명의 제1 흡착 필터, 제2 흡착 필터 및 제3 흡착 필터는 부직포 형태의 섬유재로, 제1 흡착 필터, 제2 흡착 필터 및 제3 흡착 필터는 중금속 흡착 조성물이 도포되는 것이다.The first adsorption filter, the second adsorption filter, and the third adsorption filter of the present invention are non-woven fabrics, and the first adsorption filter, the second adsorption filter, and the third adsorption filter are coated with a heavy metal adsorption composition.
상기 제1 흡착 필터, 제2 흡착 필터 및 제3 흡착 필터는 시트형, 두루말이 담체형 및 지구본 담체형으로 형성될 수 있으며, 그 크기와 형태는 제한하지 않고, 해당 분야에서 통상의 지식을 가진 자가 사용할 수 있는 모든 형태를 포함하는 것으로 정의한다.The first adsorption filter, the second adsorption filter, and the third adsorption filter may be formed in the form of a sheet, a roll carrier, and a globe carrier, and the size and shape are not limited, and it is defined as including all forms that can be used by those skilled in the art.
상기 시트형의 경우, 상기 부직포 형태의 섬유재를 직접 부직포로서 형성하거나 상기 섬유재보다 용융온도가 높은 별도의 부직포를 사용하여 그 내부에 중금속 흡착 조성물을 충전시킬 수 있으며, 롤(roll)형태가 가능하여 폭과 깊이를 자유롭게 조절할 수 있고, 담체의 교체가 용이하도록 할 수 있다.In the case of the sheet type, the fiber material in the form of a non-woven fabric may be directly formed as a non-woven fabric or a separate non-woven fabric having a higher melting temperature than the fiber material may be used to fill the inside of the heavy metal adsorption composition, and the width and depth may be freely adjusted due to the roll shape, and the replacement of the carrier may be facilitated.
상기 제1 흡착 필터는 활성탄 및 알칼리 세라믹을 포함하는 것이다.The first adsorption filter includes activated carbon and alkali ceramic.
상기 활성탄은 야자각, 목재류, 갈탄, 무연탄, 유연탄 등의 탄소질을 원료로 제조되는 미세 세공이 잘 발달된 무정형 탄소의 집합체로서, 활성화 과정을 통해 분자 크기 정도의 미세 세공이 형성되어 큰 내부 표면적을 가지는 흡착제이다.The activated carbon is an aggregate of amorphous carbon with well-developed micropores made of carbonaceous materials such as coconut husk, wood, lignite, anthracite, and bituminous coal, and has a large internal surface area by forming micropores of a molecular size through an activation process. It is an adsorbent.
활성탄은 1g당 1000㎡ 이상의 큰 내부 표면적을 가지며, 이 내부 표면에 존재하는 탄소원자의 관능기가 주위의 액체 또는 기체에 인력을 가하여 피 흡착질의 분자를 흡착하는 성질이 있다. 이러한 흡착성으로 인해 활성탄은 높은 흡착성을 지닌 탄소질 물질, 목탄 따위를 활성화하여 만드는 것으로, 다공질이어서 공기정화 뿐만 아니라, 색소나 냄새를 잘 빨아들이므로, 탈색, 정제, 촉매, 방독면 또는 수처리, 식품, 음료수, 의약의 가공과 같은 다양한 분야에서 정제를 위해 사용되고 있다.Activated carbon has a large internal surface area of 1000 m 2 or more per 1 g, and functional groups of carbon atoms present on the internal surface have the property of adsorbing molecules of an adsorbate by applying an attractive force to the surrounding liquid or gas. Due to this adsorption, activated carbon is made by activating a carbonaceous material with high adsorption, such as charcoal. It is porous and absorbs pigments and odors as well as air purification because it is porous.
상기 알칼리 세라믹은 pH가 6.0 내지 8.0인 세라믹을 이용한 것으로, 폐산성물의 중화와 중화 후 발생하는 부산물을 함유하는 중금속의 흡착 효과를 나타내기 위함이다.The alkaline ceramic uses a ceramic having a pH of 6.0 to 8.0, and is intended to exhibit neutralization of waste acid and an adsorption effect of heavy metals containing by-products generated after neutralization.
본 발명의 세라믹은 황토인 것으로, 상기 황토는 실리카(SiO2), 알루미나(Al2O3), 철분, 마그네슘(Mg), 나트륨(Na) 및 무기질이 함유된 미세입자로, 인체에 유익한 미네랄을 가지고 있고, 오랜 기간 축적된 토양 미생물과 효소작용에 의한항균·방충·탈취효과 및 오염 물질 제거 효과 등을 가지는 특징이 있다. The ceramic of the present invention is ocher, and the ocher is fine particles containing silica (SiO 2 ), alumina (Al 2 O 3 ), iron, magnesium (Mg), sodium (Na) and minerals, and has minerals beneficial to the human body, and has antibacterial, insect repellent, deodorizing and pollutant removal effects by soil microorganisms and enzymes accumulated over a long period of time.
이에 본 발명의 제1 흡착 필터는 부직포 형태의 섬유재에 활성탄 및 알칼리 세라믹을 포함하는 것으로, 오염수 이물질 및 일부 이온성 이물질 등의 유해물질을 제거하는 것이다.Accordingly, the first adsorption filter of the present invention includes activated carbon and alkali ceramics in a fibrous material in the form of a non-woven fabric, and removes harmful substances such as contaminated water foreign substances and some ionic foreign substances.
상기 제2 흡착 필터는 키토산을 포함하는 것이다.The second adsorption filter includes chitosan.
상기 키토산은 다수의 아민기가 형성되어 전이금속과 결합할 수 있는 킬레이팅(chelating) 특성으로 인해 배위결합을 하여 착제(complex)를 형성하기 때문에, Cd, Hg, Pb, Ni, Cr 등과 같은 유해한 중금속 이온을 포집하는데 사용되고 있다. Since the chitosan forms a complex through coordination bonding due to its chelating property capable of bonding with a transition metal through the formation of a large number of amine groups, it is used to trap harmful heavy metal ions such as Cd, Hg, Pb, Ni, Cr, etc.
또한, 키토산 분자 중 -NH2 기는 물속에 녹아있는 양이온인 카드뮴, 망간, 아연이온과 배위 결합하여 대부분 제거할 수 있다.In addition, the -NH 2 group in the chitosan molecule can be mostly removed by coordinated bonding with cations such as cadmium, manganese, and zinc dissolved in water.
키토산의 원료가 되는 키틴은 게, 새우 등 갑각류의 외골격, 곤충류의 표피, 균류의 세포벽에 널리 분포되어 있는 효모 다당류로서, 폴리-β(1,4)-N-아세틸-D-글루코사민을 기본 단위로 하여 이루어진 다당류이다. 키틴은 그 구조가 셀룰로오스와 유사하나, 화학적 성질 및 물성은 전혀 다르며, 물 또는 유기용매에 대한 용해도가 매우 낮은 특징이 있다.Chitin, which is a raw material of chitosan, is a yeast polysaccharide widely distributed in the exoskeleton of crustaceans such as crabs and shrimps, the epidermis of insects, and the cell walls of fungi. Chitin has a structure similar to that of cellulose, but has completely different chemical and physical properties, and has very low solubility in water or organic solvents.
상기 키틴의 탈 아세틸화 과정에 의해 형성되는 키토산은 희석된 산에 용해되지만, 통상 분자량이 300,000 내지 3,000,000의 고분자 상태로 용해되어 사용되고 있고, 이 경우 점도가 매우 높은 양 이온성 용액이 된다. 이와 같은 키토산은 다양한 분야에 이용되고 있으며, 식품 첨가물, 흡수제, 지방 결합제, 유화 안정제, 중금속 흡착제, 유산균 촉진제, 다이어트제, 항콜레스테롤제, 면역 활성제, 항균제 및 보존제에 사용되고 있다.Although chitosan formed by the deacetylation of chitin is dissolved in diluted acid, it is usually dissolved in a polymer state with a molecular weight of 300,000 to 3,000,000, and in this case, it becomes a cationic solution with a very high viscosity. Such chitosan is used in various fields, and is used in food additives, absorbents, fat binders, emulsion stabilizers, heavy metal adsorbents, lactic acid bacteria promoters, diet agents, anticholesterol agents, immune activators, antibacterial agents and preservatives.
이에 본 발명의 제2 흡착 필터는 부직포 형태의 섬유재에 키토산을 포함하는 것으로, 오염수에 포함된 중금속을 제거할 수 있다. Accordingly, the second adsorption filter of the present invention includes chitosan in a fiber material in the form of a non-woven fabric, and can remove heavy metals contained in contaminated water.
바람직하게 상기 제2 흡착 필터는 10 mesh 내지 100 mesh의 크기인 키토산 비드를 포함하는 것이며, 키틴으로부터 85% 이상 탈 아세틸화된 것이다.Preferably, the second adsorption filter includes chitosan beads having a size of 10 mesh to 100 mesh, and is deacetylated from chitin by 85% or more.
상기 크기의 키토산 비드를 이용하는 경우, 다수의 아민기를 포함하여 중금속 제거에 효율적일 수 있으며, 키토산을 이용하여 중금속을 제거하는 필터 제조 시 통수능과 장시간 사용하더라도 중금속 제거 효율이 일정하게 유지될 수 있다.When chitosan beads having the above size are used, they contain a plurality of amine groups and can be effective in heavy metal removal, and when preparing a filter for removing heavy metals using chitosan, the water passing ability and heavy metal removal efficiency can be maintained constant even after long-term use.
또한, 키틴으로부터 85% 이상 탈 아세틸화되는 경우, 카드뮴, 망간, 아연 철, 납, 수은, 구리, 셀레늄, 6가크롬, 비소 등의 중금속이 80% 이상 제거될 수 있다.In addition, when 85% or more of chitin is deacetylated, 80% or more of heavy metals such as cadmium, manganese, iron zinc, lead, mercury, copper, selenium, hexavalent chromium, and arsenic can be removed.
상기 제3 흡착 필터는 은나노를 포함하는 것이다.The third adsorption filter includes silver nano.
상기 은나노는 은의 나노미터 입자 형태로, 은 이온(Ag+)이 세균 및 박테리아 세포막을 산화시켜 항균 활성을 나타낸다. 본 발명의 제3 흡착 필터는 상기 은나노를 포함하여 항균 활성을 나타내는 것이다.The silver nano is in the form of silver nanometer particles, and silver ions (Ag+) oxidize bacteria and bacterial cell membranes to exhibit antibacterial activity. The third adsorption filter of the present invention includes the nano-silver and exhibits antibacterial activity.
본 발명의 제1 흡착 필터, 제2 흡착 필터 및 제3 흡착 필터는 중금속 흡착 조성물이 도포되는 것으로, 중금속 흡착 효과를 높이는 동시에, 필터 자체에 항균 성능을 부여할 수 있다.The first adsorption filter, the second adsorption filter, and the third adsorption filter of the present invention are coated with a heavy metal adsorption composition, and can enhance the heavy metal adsorption effect and impart antibacterial performance to the filter itself.

또한, 상기 제1 흡착 필터는 본 발명의 중금속 흡착 조성물을 도포함으로써 부직포 형태의 섬유재에 활성탄 및 알칼리 세라믹이 용출되는 것을 방지할 수 있다.In addition, the first adsorption filter can prevent the elution of activated carbon and alkali ceramics from the non-woven fiber material by applying the heavy metal adsorption composition of the present invention.
상기 제2 흡착 필터의 경우, 부직포 형태의 섬유재에 키토산을 포함하여, 오염수에 포함된 중금속을 제거하는 동시에, 본 발명의 중금속 흡착 조성물을 추가적으로 도포하여, 항균 활성을 나타내는 것이다.In the case of the second adsorption filter, chitosan is included in a fibrous material in the form of a non-woven fabric to remove heavy metals contained in contaminated water, and at the same time, the heavy metal adsorption composition of the present invention is additionally applied to exhibit antibacterial activity.
또한, 상기 제2 흡착 필터는 본 발명의 중금속 흡착 조성물을 도포함으로써 부직포 형태의 섬유재에 키토산이 용출되는 것을 방지할 수 있다.In addition, the second adsorption filter can prevent chitosan from being leached into a fiber material in the form of a nonwoven fabric by applying the heavy metal adsorption composition of the present invention.
상기 제3 흡착 필터의 경우, 부직포 형태의 섬유재에 은나노를 포함하여, 물속에 항균 효과를 나타내는 것으로, 본 발명의 중금속 흡착 조성물을 추가적으로 도포하여, 항균 효과를 높일 수 있는 것이다.In the case of the third adsorption filter, since nano-silver is included in the fiber material in the form of a non-woven fabric, the antibacterial effect is exhibited in water, and the antibacterial effect can be enhanced by additionally applying the heavy metal adsorption composition of the present invention.
또한, 상기 제3 흡착 필터는 본 발명의 중금속 흡착 조성물을 도포함으로써 부직포 형태의 섬유재에 은나노가 용출되는 것을 방지할 수 있다.In addition, the third adsorption filter can prevent elution of nano-silver from non-woven fiber material by applying the heavy metal adsorption composition of the present invention.

상기 중금속은 비소(As), 카드뮴(Cd), 구리(Cu), 납(Pb), 크롬(Cr), 아연(Zn), 니켈(Ni), 수은(Hg), 망간(Mn), 안티몬(Sb) 및 비스무트(Bi) 및 이들의 혼합으로 이루어지는 군에서 선택되는 것이다.The heavy metal is selected from the group consisting of arsenic (As), cadmium (Cd), copper (Cu), lead (Pb), chromium (Cr), zinc (Zn), nickel (Ni), mercury (Hg), manganese (Mn), antimony (Sb) and bismuth (Bi), and mixtures thereof.
상기 비소(As)는 수계환경과 토양환경에서 검출되는 비금속성 원소(metalloid)로서 다른 원소와 결합한 형태로 일반적으로 발견된다. 비소는 자연계의 일반적인 수계 환경에서 AsO2 -1의 형태로 존재한다. 비소를 포함하고 있는 광물은 매우 다양한데, 비소는 종종 납(Pb), 수은(Hg), 주석과 같은 금속들과 화합물을 형성하기도 하고 철, 니켈(Ni), 황과 결합된 화합물로 존재한다. 비소는 특히 FeAsS(Arsenopyrite 또는 Mispickel), As4S4(Realgar) 및 As2S3(Orpiment)와 같은 Fe광물과 황화합물에 농축되어 있는 경우가 많다.The arsenic (As) is a non-metallic element (metalloid) detected in aquatic and soil environments and is generally found in a form combined with other elements. Arsenic exists in the form of AsO 2 -1 in a common aqueous environment in nature. There are a wide variety of minerals containing arsenic. Arsenic often forms compounds with metals such as lead (Pb), mercury (Hg), and tin, and exists as a compound with iron, nickel (Ni), and sulfur. Arsenic is often concentrated in Fe minerals and sulfur compounds, particularly FeAsS (Arsenopyrite or Mispickel), As 4 S 4 (Realgar) and As 2 S 3 (Orpiment).
또한, 비소는 무기태 비소와 유기태 비소로 구분된다. 유기태 비소는 비소가 탄소와 수소와 결합되어 있다는 것을 의미하는데, 주로 Cocodylic Acid(Dimethylarsenic Acid or DMA)의 형태로 토양에 존재하고, 많은 식품들의 미량 구성요소로 존재하기도 한다. 무기태 비소는 인체건강에 더 큰 악영향을 주는데, 가장 대표적인 무기태 비소가 3가 비소(-3가(價)를 띠는 비소, Arsenite, 아비산염)와 5가 비소(Arsenate, 비산염)의 형태로 존재하게 된다. 즉 산화된 환경조건에서는 비산염(Arsenate)이 주된 화학종이고, 환원된 환경조건에서는 아비산염(Arsenite)이 주된 형태이다.Also, arsenic is classified into inorganic arsenic and organic arsenic. Organic arsenic means that arsenic is combined with carbon and hydrogen, and it is mainly present in soil in the form of Cocodylic Acid (Dimethylarsenic Acid or DMA), and it is also present as a trace component in many foods. Inorganic arsenic has a greater adverse effect on human health, and the most representative inorganic arsenic exists in the form of trivalent arsenic (arsenite, arsenic acid) and pentavalent arsenic (arsenate, arsenic acid). That is, in oxidized environmental conditions, arsenate is the main chemical species, and in reduced environmental conditions, arsenite is the main form.

The Itai-itai disease is a representative symptom of cadmium poisoning, and is a cadmium pollution disease that occurred in the lower reaches of the Jinzu River in Toyama Prefecture, Japan. In the beginning, you may not feel the danger because there are no obvious symptoms, but the main symptom is that the bones become soft as they accumulate in the bones instead of calcium. In addition, dyspnea, chest tightness, and poor cardiopulmonary function appear, and if it continues, death may occur. Zinc has the effect of removing lead, a harmful heavy metal, and when cadmium accumulates, zinc cannot play its role in the nervous system, causing itai-itai disease.

Exposure to this material can cause skin diseases, diarrhea, gastritis, vomiting, indigestion, duodenitis, insomnia, anemia, headache, rhinitis, bronchitis, asthma, mild fibrosis, and various respiratory-related diseases. According to some studies, it can cause myocardial infarction, stroke, respiratory cancer, and kidney failure.
