2. The impact on the environment
a health hazard

right fetus : toxic to the fetus eyes, ears and other development will be affected.
of animals : rats to inhalation of the goods heated to 170 ° C by the release of volatile product of two hours, did not cause animals to death; 4-hour exposure of rats were all dead.
right : engaged in the production of goods and Phthalocyanine dibutyl two workers, has eyes and upper respiratory tract irritation symptoms.
on skin and eyes role : right animal and human skin and eye mucosa without stimulating effect. By the integrity of skin can absorb a small amount. The guinea pig is not cause sensitization. People can cause mild sensitization.

high concentration of relatively short-term exposure hazards :
eye contact : Occasionally after exposure are not treated no residue hazards.
Inhalation : Occasionally after exposure are not treated no residue hazards.
skin penetration : Occasionally after exposure are not treated no residue hazards.
skin irritation : Occasionally after exposure are not treated no residue hazards.
service income : Occasionally after exposure are not treated no residue hazards.

two, toxicology information and environmental behavior

acute toxicity : LD₅₀6513mg/kg (mice by mouth); Fed (mice); LC₅₀5000 mg/m3 (mice inhaled) < / P>

in the environment of migration : the phthalate esters, hydrolysis, volatile role and photolysis role is not the important reaction process. It is estimated phthalate esters from the hydrolysis half-life of two ethyl phthalate esters to 3.2 phthalate 2-ethylhexyl ester 2000. Because of its low vapor pressure, the loss is very small volatile, or almost no volatilization losses. Although it is not to see the phthalate esters and photolysis of reports, but in accordance with its ultraviolet, visible within no absorption spectra of this phenomenon can be inferred that they are difficult for the photochemical reaction. Experimental studies have shown that the biological phthalate esters are depleted, this conclusion was the scene of the findings are confirmed, as the experimenter found aquatic organisms are obvious such compounds residues.
