The material was collected during the open water period from March to end of November 2019. In our research in basin Chirchik river (Boshkizylsay river, Ugam (pre-settlement site), river) were discovered several types zoobenthos and periphyton. monitoring carried out on 8 stations, total 64 quantitative samples macrozoobenthos periphyton taken. Anthropogenic pollution causes changes composition...

Beach erosion is a widespread phenomenon on Caribbean beaches, with rates of coastline retreat between 2.2 and 0.5 m/year higher reports in some areas. Different investigations indicate the combination natural anthropogenic causes highlight current influence climate change related sea level rise. It recorded as generalizing trend landward displacement beach profile, sand transfer above dunes ba...

OBJECTIVES We documented causes of mortality in an opportunistic sample of golden eagles, turkey vultures and common ravens, and assessed exposure to several contaminants that have been found in carrion and common prey for these species. METHODS Dead birds were submitted for testing through wildlife rehabilitation centres and a network of wildlife biologists in California from 2007 to 2009. ...

Humans have a profound effect on fire regimes by increasing the frequency of ignitions. Although ignition is an integral component of understanding and predicting fire, to date fire models have not been able to isolate the ignition location, leading to inconsistent use of anthropogenic ignition proxies. Here, we identified fire ignitions from the Moderate Resolution Imaging Spectrometer (MODIS)...

[1] The anthropogenic CO2 accumulation rate for the North Atlantic Ocean was estimated on the basis of the decrease in the dC of the dissolved inorganic carbon measured between cruises in 1981 (Transient Tracers in the North Atlantic), 1993 (OACES) and 2003 (Repeat Hydrography). A mean depth-integrated dC change of 15.0 ± 3.8% m yr 1 was estimated by applying a multiple linear regression approa...

A Lagrangian approach based on a physical-biogeochemical modeling was used to compare the potential transfer of cadmium (Cd) from natural and anthropogenic sources to plankton communities (Cd-uptake) in the North-West African upwelling. In this region, coastal upwelling was estimated to be the main natural source of Cd while the most significant anthropogenic source for marine ecosystem is prov...

Distributions of anthropogenic signatures (impacts and activities) are mathematically analysed. The aim is to understand the Anthropocene and to see whether anthropogenic signatures could be used to determine its beginning. A total of 23 signatures were analysed and results are presented in 31 diagrams. Some of these signatures contain undistinguishable natural components but most of them are o...

Mercury is released in the environment by various natural and anthropogenic activities. As mercury toxic, presence of high levels a major concern. One source humans dental amalgam fillings. Dental has been used for ages clinics hospitals restoring defective decayed teeth. This raises concern regarding use its disposal. The purpose this article to sensitize people about hazards mercury, make the...
