Check use of banned pesticides, court tells government

The Delhi High Court Thursday directed the central and Delhi governments to finalise steps within two months to prevent the rampant use of banned pesticides in vegetables and fruits that poses health threat to people. 

Sydney: A new screening tool could help detect pesticide traces instantly in large water samples.

The tool, developed by Australian doctoral research student David Beale is based on chemiluminescence -- a highly-sensitive technique that reveals the presence of minute quantities of an organic compound.

Beale undertook the project as part of his doctoral research at the Royal Melbourne Institute of Technology's School of Applied Sciences.

"Typical pesticide monitoring involves collecting samples on site then taking them back to a laboratory for analysis, a process that can take several days.

 

"By instantly identifying the presence of specific pesticide residues, this new method would enable water utilities to find out on the spot if a water catchment is contaminated," said a statement from the Melbourne Research Institute.

"I hope my work could enable water utilities to catch any contamination early, as well as boosting the amount of testing conducted within our water catchments," Beale said.
