알드린 C화학적 특성, 용도, 생산
물성
분자량 364.93인 갈색 또는 무색 무취의 결정체로 약산, 약알칼리 용액의 200℃ 이상에서도 안정하나 산화제나 진한 산에는 분해를 일으킨다. 또한 아세톤, 벤젠, 크실렌 등에 용해된다.
개요
알드린은 유기염소계의 토양해충 살충제의 일종으로 채소 해충, 보리 해충 등에 살충제 및 살균제로 사용된다. 알드린은 체내 또는 환경 중에서 매우 빠르게 디알드린(Dieldrin)으로 분해된다. 따라서 알드린과 디알드린은 일반적으로 같이 다루게 된다. 순수한 알드린은 흰색의 화학취를 나타내는 가루이다. 자연적으로 환경에서 생성되지는 않으며, 1950년대에서 70년대까지 옥수수와 면화와 같은 작물의 살충재로 광범위하게 사용되었으나, 위해가 밝혀지고 사용이 중단되었다. 우리나라도 현재 사용을 금지하고 있는 살충제 성분이다.
용도
흰개미(termites), 옥수수 뿌리충(corn rootworms), 옥수수씨 딱정벌레 (seed corn beetle), 옥수수씨 구더기(seed corn maggot), 구렁방아벌레 (wireworms), 바구미(rice water weevil), 베짱이(grasshoppers), 일본딱정벌레 (Japanese beetles)의 제거를 위하여 살충제로 쓰이거나 흰개미(termite)의 공격을 억제하여 목재물의 보호에 쓰인다.
독성
작업장 등에서 분진으로 어느 정도의 량의 알드린을 장기간 흡입하였을 경우 구토, 두통, 현기증, 메스꺼움, 경련 등의 증세를 일으킬수 있으며, 이러한 경우 이러한 원인을 제거하고 나면 대부분의 경우 빠른 긴간에 회복될 수 있다. 동물실험에서도 고농도의 알드린 또는 디알드린에 노출시켰을 경우 신경계에 영향이 있는 것으로 관찰되었다. 따라서 알드린과 같은 화합물을 취급하는 근로자는 작업시 방진 마스크, 보안경, 보호의, 보호장갑을 착용하여야 한다.
화학적 성질
off-white solid
물리적 성질
Colorless to white, odorless crystals when pure; technical grades are tan to dark brown with a
mild, characteristic chemical odor. The odor threshold concentration in water is 17 μg/kg
(Sigworth, 1964).
용도
Aldrin has been used as an insecticide for soil insects and the
control of termites around buildings. Industrial exposures
occur among groups that have been involved in the manufacture
of aldrin, and in the handling and spraying of suspensions
and emulsions of this compound.
정의
ChEBI: An organochlorine compound resulting from the Diels-Alder reaction of hexachlorocyclopentadiene with norbornadiene. It was widely used as an insecticide before being banned in the 1970s as a persistent organic pollutant.
일반 설명
Aldrin, cast solid is a brown to white solid. If the large pieces are broken up or powdered, ALDRIN is toxic by inhalation and skin absorption. ALDRIN is insoluble in water and noncombustible. ALDRIN is used as an insecticide.
공기와 물의 반응
Insoluble in water.
반응 프로필
ALDRIN may be sensitive to prolonged exposure to light. ALDRIN is stable to heat and in the presence of inorganic and organic bases. ALDRIN is stable to hydrated metal chlorides and mild acids. ALDRIN is thermally stable up to 392° F and ALDRIN is stable between pH 4 and 8. ALDRIN reacts with concentrated acids and phenols in the presence of oxidizing agents. ALDRIN can be corrosive to metals. ALDRIN can react with acid catalysts, acid oxidizing agents and active metals.
위험도
Toxic by skin absorption. Central nervous
system impairment, and liver and kidney damage.
Questionable carcinogen.
건강위험
Poisoning by aldrin usually involves convulsions due to its effects on the central nervous system. Reproductive effects and liver effects have also been reported. It is classified as an extremely toxic chemical. Probable oral lethal dose for humans is between 7 drops and one oz. for a 150 lb. adult human. Conflicting reports of carcinogenicity of ALDRIN remain an area of controversy. Similar chemically and toxicologically to dieldrin.
화재위험
When heated to decomposition, ALDRIN emits toxic fumes of chlorine containing compounds. Commercial solutions may contain flammable or combustible liquids. The dry powder will not burn. Container may explode in heat of fire. Avoid concentrated mineral acids, acid catalysts, acid oxidizing agents, phenols, or active metals.
Safety Profile
Suspected carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. Poison by ingestion, skin contact, intravenous, and intraperitoneal routes. Human systemic effects by ingestion: excitement, tremors, and nausea or vomiting. An experimental teratogen. Other experimental reproductive effects. Continued acute exposure causes liver damage. Human mutation data reported. See also CHLORINATED HYDROCARBONS. When heated to decomposition it emits toxic fumes of Cl-.
Carcinogenicity
Rodent carcinogenicity evaluations
of aldrin have been extensively reviewed, with
the conclusion that the mouse-specific hepatocarcinogenic
activity of aldrin occurs through a nongenotoxic mode of
action involving promotion of spontaneously initiated liver
cells.
