I have no literature about pesticides but some material (links) on heavy metals in environment and microbial bioremediation of metals.
I am giving you the link of science direct where I have searched some literature for my work. It contains about 100 articles. Hope these will be beneficial for you.
Some of the articles are fully accessed at our institution if you need some (depending upon your interest) and cant access those articles, I will send you the full text of those accessible articles.
