OBJECTIVES The aim of the present project was to assess population exposure to pesticides in the vicinity of pesticide dump sites and make a preliminary evaluation of the potential health hazards to humans. MATERIALS AND METHODS Of the 286 pesticide dump sites registered in Poland, 40 were selected as the largest source of ecological hazard. The application of the Hazard Ranking System made i...

False cleavers (Galium spurium L.) is an annual broadleaf weed, commonly found in cereal crops around the world. It reduces crop yields mainly by competition for nutrients and plant lodging, which decreases photosynthetic rate of cultivated plants. Two field experiments were carried out different locations to examine efficacy post-emergence herbicides against false durum wheat (Triticum Desf.)....

Adsorbents presenting high adsorption capacity, fast rate, easy regeneration, and a good possibility for reusability are ideal removing 4-chloro-2-methyl-phenoxyacetic acid (MCPA) or other pesticides from wastewater. Here, the effects of regeneration treatments on adsorption–desorption cycles examined using two commercial activated carbons (ACs) (Merck Norit 1240 X). MCPA was Merck ACs in powde...

2-methylphenoxyacetic acid (2-MPA), 2-methyl-4-chlorophenxyacetic acid (MCPA) and 4-chlorophenoxyacetic acid (4-CPA) were imprinted to investigate the cross-selectivities of molecularly imprinted polymers (MIPs). The result indicates that 2-MPA, which is similar in shape, size and functionality with phenoxyacetic herbicides, are suitable to be used as a suitable template to prepare the MIPs for...

Since the discovery of the herbicidal action of growth regulators such as 2,4-dichlorophenoxyacetic acid (2,4-D), there has been much information obtained concerning the herbicidal mechanism. The action of 2,4-D on organization, physiology and chemical changes of cells and tissues has been studied (6, 7, 8, 9, 10). Several experimenters (2, 5, 6, 9) on different plants have found that 2,4-D ind...

Since transgenic, bromoxynil-resistant cotton and glufosinate-resistant canola were introduced in 1995, planting of transgenic herbicide-resistant crops has grown substantially, revolutionizing weed management where they have been available. Before 1995, several commercial herbicide-resistant crops were produced by biotechnology through selection for resistance in tissue culture. However, non-t...
