Dear Sutanu,

Beta lactam  & Pesticide residues are important for culture ponds, bio accumulation of polyaromatic hydro carbon (PAH) levels in marine waters are emerging issues related to aquatic pollution. You can ref. this article also 

International Soil and Water Conservation Research,(2015) Volume 3, Issue 1, Pages 57–65.

Sutanu,

I agree with Martin, any of the newer pesticides classes ( nicotinoids or orpyrethroid) would be good candidates for toxicity studies

midacloprid

 Thiamethoxam  Clothianidin Dantosu,  Dantop,Acetamiprid 

Thiacloprid Dinotefuran Nitenpyram 

Pyrethroids

permethrin, cypermethrin and deltamethrin. fenvalerate, lambda-cyhalothrin and beta-cyfluthrin

all the new pharmaceuticals, nanoparticles, microplastics and EDCs are the emerging contaminants.

The presence of soots generated from the burning of hydrocarbons and waste from Petrol

Hello,

Plastic nano residues are gaining attention all over the world as emerging contaminants in ocean waters.

I agreed with Martin sir, from recent years plastics nano residual is considered as emerging contaminants creating major problem in ocean. It is new area for research.

I agree totally with Martin that plastic nano residues are gaining attention as contaminants in ocean waters. These nano particles that are not easily broken down may have their way in causing genetic changes if they find their way in to the genetic make up of some organisms that may be expose to them especially those filtering organisms. There is need to pay attention to its presence now.
