Document Summary
30% of quesions from lecture #9 will be on the inal exam. More concerned with nitrogen ferilizers, seen in water. In ferilizers you have nitrites (no3) which are used in soil no3 converts into no2 = toxic (causes blue baby syndrome/methemoglobinemia) Some say rats and squirrels are from the same group when using pesicide approach but we usually refer to insects on the crops. Insecicide: inorganic/organic compounds + natural sources (i. e. extract from other plants that are found to be resistant on some insects). Chemicals in the leaves that ight against the insects which is why insects don"t like to eat them (i. e. pyrethrum). Organophosphate + carbamate = organic compounds direct spray they are not very toxic. Herbicides can go into animal foods, livestock and can contaminate meat supply. Individuals who work in the industry, farmers + families (users) and seasonal workers are highly exposed (foreign borne and/or hispanics)
