Microplastic evidence assessment from water and sediment sampling in a shallow tropical lake.

Microplastics (MPs) severely threaten inland waterbodies due to the direct impact of human activities. In the present study, spatial and temporal patterns of MPs in a shallow tropical lake were assessed, describing their size, morphology, and polymer types. Water and sediment samples were collected from Lake Chapala during three seasons, and MPs were quantified with a stereomicroscope.

Reduction in Salt Stress Due to the Action of Halophilic Bacteria That Promote Plant Growth in .

Soil salinity is one of the most important factors reducing agricultural productivity worldwide. Halophilic plant growth-promoting bacteria (H-PGPB) represent an alternative method of alleviating saline stress in crops of agricultural interest. In this study, the following halophilic bacteria were evaluated: sp.

Identification of Halophilic and Halotolerant Bacteria from the Root Soil of the Halophyte Raf.

Soil salinity is a condition that limits crop growth and productivity, and soil-dwelling bacteria from halophytic plant roots may be a viable strategy to cope with low productivity due to salt stress. Halophilic and halotolerant bacteria of the root soil of were analyzed in this study as there is little evidence regarding its associated microbiology. Soil was sampled from the roots of to obtain the cultivable bacteria.

Bioaccumulation of PCBs and PBDEs in Fish from a Tropical Lake Chapala, Mexico.

Lake Chapala is the largest natural freshwater reservoir in Mexico and the third largest lake in Latin America. Lakes are often considered the final deposit of polluting materials; they can be concentrated in the organisms that inhabit them, the water, and the sediments. The PCBs and PBDEs are environmental pollutants highly studied for their known carcinogenic and mutagenic effects.

Quantitative Analysis of Rutin by HPTLC and In Vitro Antioxidant and Antibacterial Activities of Phenolic-Rich Extracts from .

A. Gray, like other wild plants of the genus , has been used in herbal medicine. There is information for other species of the genus related to their phenolic content, antioxidant capacity, and isolation of bioactive compounds with antimicrobial activity.

Biosaline agriculture: an agronomic proposal for onion ( L.) production.

The onion crop with brackish irrigation but accompanied by halophytes is productive, so halophytoremediation is an excellent agronomic proposal for areas where there is poor quality water used for irrigation.

Phenolic Profile, Antioxidant and Anti-Proliferative Activities of Methanolic Extracts from Cav. Leaves.

Cav. (Apocynaceae) is a shrubby plant endemic of Mexico which has been used in traditional medicine. However, the bioactive potential of this plant remains unexplored.

Potential of (L.) Wettst and Raf. as an agronomic management alternative to recover the productivity of saline soils.

Water scarcity and increasing salinity are the main limiting environmental factors directly affecting the establishment and development of agroecosystems. The objective of this study was to assess the capacity of the halophytes (L.) Wettst and Raf.

Scenarios of availability of water due to overexploitation of the aquifer in the basin of Laguna de Santiaguillo, Durango, Mexico.

Background: The importance of water to life is unquestionable. Most of the fresh water we use for daily activities comes from the aquifers, which in many cases due to misuse are overexploited and at risk. This article studies the aquifer that appeared in Laguna de Santiaguillo basin; it should be noted that the most important economic activity in the basin is agriculture.

Tracking Metal Pollution in Lake Chapala: Concentrations in Water, Sediments, and Fish.

We measured concentrations of selected metals (Al, Ba, Cu, Mn, Hg, Sr, V, and Zn) in water, sediments, and fish from Lake Chapala and a reference site to evaluate potential negative effects on wildlife, particularly fish-eating birds. Fish metal concentrations ranged from 0.05 µg/g wet weight (ww) for Al and Cu to 64.

Accumulation and hazard assessment of mercury to waterbirds at Lake Chapala, Mexico.

Lake Chapala is the largest tropical lake in Mexico. The objectives of this study were to determine bioaccumulation of Hg in fish and to evaluate the potential impacts of Hg in the diet of aquatic birds, particularly the American white pelican (AWPE), in Lake Chapala. Hg concentrations in three fish species ranged from 0.

Eisenia fetida increased removal of polycyclic aromatic hydrocarbons from soil.

The removal of phenanthrene, anthracene and benzo(a)pyrene added at three different concentrations was investigated with or without earthworms (Eisenia fetida) within 11 weeks. Average anthracene removal by the autochthonous micro-organisms was 23%, 77% for phenanthrene and 13% for benzo(a)pyrene, while it was 51% for anthracene, 47% for benzo(a)pyrene and 100% for phenanthrene in soil with earthworms. At 50 and 100mg phenanthrene kg(-1)E.
