Pollution of the aquatic environment is an ever-growing problem, as waters are the ultimate sink for the large number of xenobiotics from multiple sources. DNA damaging agents have a significant ecological relevance since they are implicated in many pathological processes and exert effects beyond that of individual being active through following generations. A large number of methods have been ...

Landfilling is the oldest method of waste management. A number biological, chemical, and physical reactions occur at landfills, which cause a threat to environment. For this reason, landfill monitoring necessary, biomonitoring increasingly beginning be used. The aim study (i) determine some effects on surrounding environment, (ii) analysis plant bioindicators (iii) based occurrence species prod...

conclusions pine trees can be used as a worthy bio-indicator for hms pollution monitoring in the ambient air in areas with extensive vegetation of pine trees. results iron had the highest concentration (345.0053 mg/kg) in leaves when compared with other hms. the concentration of zn, cu, pb and cd were 26.1384, 5.5905, 2.9963 and 0.7383 mg/kg, respectively. spatial mapping indicated that industr...

BACKGROUND Isocyanates are some of the leading occupational causes of respiratory disorders, predominantly asthma. Adequate exposure monitoring may recognize risk factors and help to prevent the onset or aggravation of these aliments. Though, the biomonitoring appears to be most suitable for exposure assessment, the sampling time is critical, however. In order to settle the optimal time point f...

BACKGROUND In keeping with the fundamental practice of transparency in the discussion and resolution of ethics conflicts raised by research, a summary of ethics issues raised during Portuguese biomonitoring in health surveillance and research is presented and, where applicable, their resolution is described. METHODS Projects underway aim to promote the surveillance of public health related to...

The COI gene, colloquially named the DNA barcode, is a universal marker for species identification in animal kingdom. Nevertheless, due to taxonomic impediment, there are various proposals molecular operational units (MOTUs) because high-throughput sequencers can generate millions of sequences one run. In case freshwater systems, it possible analyze whole communities through their using only wa...
