Periphyton responses to non-point pollution in a natural eutrophic condition in Pampean streams
(E Schweizerbartsche Verlags, 2013-07)
The aim of this study was to examine the effects of different intensities of non-point pollution on water quality and the periphyton community in natural eutrophic environments such as the Pampean streams. Non-point pollution ...
Efeitos espaço temporais da poluição pontual e não pontual em uma bacia hidrográfica subtropical : ecohidrologia como ferramenta de controle
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERNCâmpus São Carlos, 2015-07-27)
Contaminants are introduced into aquatic ecosystems, both from point and diffuse sources and usually are deposited in the sediments of lakes and reservoirs. The input of diffuse pollutants in the environment is of difficult ...
Periphyton Responses to non-point Pollution in Eutrophic-Humic Environments: An Experimental Study
(Univ Tehran, 2014-06)
We proposed to use artificial channels in laboratory assays to expose periphyton to substances released in rural environments in order to test the following hypotheses 1) a high concentration of humic substances decreases ...
Effects of maize cultivation on nitrogen and phosphorus loadings to drainage channels in Central Chile
(Springer, 2015)
There are concerns about the impact of maize cultivation with high applications of nitrogen (N) and phosphorus (P) on water quality in surface waters in Mediterranean Central Chile. This study estimated the contribution ...
Using a non-homogeneous Poisson model with spatial anisotropy and change-points to study air pollution data
(Springer, 2019-06-01)
A non-homogeneous Poisson process is used to study the rate at which a pollutant's concentration exceeds a given threshold of interest. An anisotropic spatial model is imposed on the parameters of the Poisson intensity ...

Thyroid cancer incidence in women and proximity to industrial air pollution sources: a spatial analysis in a middle size city in Colombia
(Turkish National Committee for Air Pollution and Control, 2018-05)
Manizales, a mid-size city in Colombia, hosts industries like metallurgy, electrical, chemical, and rubber and plastic industrial facilities that have released into atmosphere some pollutants postulated as thyroid cancer ...
Using non-homogeneous Poisson models with multiple change-points to estimate the number of ozone exceedances in Mexico City
(JOHN WILEY & SONS LTDLONDON, 2011)
In this paper, we consider some non-homogeneous Poisson models to estimate the probability that an air quality standard is exceeded a given number of times in a time interval of interest. We assume that the number of ...
