BIOLOGICAL ACTIVITY OF SULFUR NANOPARTICLES OBTAINED FROM SODIUM POLYSULFIDE AQUEOUS SOLUTIONS [PDF]
Studied the process of the formation of nanoparticles sulfur obtained by mixing polysulfides with of organic and inorganic acids solutions. We revealed a significant acceleration of the growth of plants with the introduction of nanoparticles sulfur in ...

Can we predict community-wide effects of herbicides from toxicity tests on macrophyte species? [PDF]
Macrophyte communities play an essential role in the way freshwater ecosystems function. It is thus of great concern to understand how environmental factors, especially anthropogenic ones, influence their composition and diversity.

Sensitivity of freshwater periphytic diatoms to agricultural herbicides [PDF]
The biomonitoring of pesticide pollution in streams and rivers using algae such as diatoms remains difficult. The responses of diatomcommunities to toxic stress in streamwater are disturbed by the variations of environmental parameters.
