Question

got another evil question for ya
There are two lakes, A and B, into which industrial wastes containing
massive amounts of biodegradable hydrocarbons and arsenic pesticides
were previously discharged. Arsenic is present in its oxidized form, arsenate,
which has a high affinity to surfaces of particulate matter and so it normally
precipitates in sediments. Before the lakes are stratified during the summer
and hence their bottom zone becomes anoxic, they have almost identical
water chemistry except that in Lake A, sulfate is measured at mM
concentrations while nitrate is undetectable, and in Lake B nitrate is detected
at mM concentrations but sulfate is below detection. Based on the
perspective of microbial bioenergetics, in which lake would you expect an
arsenic contamination problem when soluble arsenic accumulates in the
water column over the summer? Please explain your answer.

Answer 1

ANSWER:

Industrial waste is the waste produced by industrial activity which includes any material that is rendered useless during a manufacturing process such as that of factories, industries, mills, and mining operations. It has existed since the start of the Industrial Revolution.^[1] Some examples of industrial wastes are chemical solvents,pigments,sludge,metals,ash,paints, sandpaper, paper products, industrial by-products, metals, and radioactive wastes.

Toxic waste, chemical waste, industrial solid waste and municipal solid waste are designations of industrial wastes. Sewage treatment plants can treat some industrial wastes, i.e. those consisting of conventional pollutants such as biochemical oxygen demand (BOD). Industrial wastes containing toxic pollutants require specialized treatment systems. (SeeIndustrial wastewater treatment
