“…Special attention must be paid to the elevated levels of boron in drinking water sources, which can have a significant impact on human health. Since boron has shown various toxicities but also beneficial effects, the toxicity of boron still remains controversial (Xu et al, 2020 ). For example, exposure to 30 g of boric acid over short time periods can affect the kidney, liver, stomach, intestines and brain, eventually leading to death (ATSDR, 2012 ).…”

Water quality characterization and assessment are key to protecting human health and ecosystems, especially in arid areas such as northern Chile, where water resources are scarce and rich in pollutants. The objective of this study was to review and assess available official water quality data in the Chilean Altiplano-Puna basins for a 10-year period (2008–2018), including water treatment systems. Within the 43,600 km 2 of Chilean Altiplano-Puna territory, only 16 official water quality monitoring stations had up-to-date data, and the sampling frequency was less than 3 per year. Most of the water samples collected at the evaluated stations exceeded the drinking and irrigation water Chilean standards for arsenic, boron, and electrical conductivity. Moreover, the characteristics of the Altiplano-Puna affect water quality inside and beyond the area, limiting water usage throughout the Altiplano-Puna basins. Drinking water treatment plants exist in urban and rural settlements; however, the drinking water supply in rural locations is limited due to the lack of adequate treatment and continuity of service. Wastewater treatment plants operate in some urban locations but rarely exist in rural locations. Limited data impede the proper assessment of water quality and thus the evaluation of the need for treatment systems. As such, the implementation of public policies that prioritize water with appropriate quantity and quality for local communities and ecosystems is imperative.

“…It has been determined that 5000-50,000 μM concentrations significantly suppressed the anchorage-dependent growth of cells. This effect could have occurred via an important pathway that plays key role in cell transformation such as SRC and PI3K/ AKT and MEK/ERK signaling pathway [20]. Diborane gas (B2H4) is a strong toxic substance for the respiratory tract.…”

The Toxicity of Environmental Pollutants

Boron is an important element found in limited resources on earth, especially in Turkey, and is essential for living organisms. Boron plays key roles in human and animal systems. While boron shows its important effects as an essential element at low concentrations in the organism, it causes different toxic effects to occur at high concentrations. There are different studies on boron and boron-containing compounds effects on organisms, toxic effects mechanisms need to be detailed. Boron and its compounds can cause toxic effects in oral, dermal, and inhalation exposure and even deadly effects at very high concentrations. The use of disinfectant and cleaning products containing boron as sprays, fertilizers, etc., during the Covid-19 pandemic also increases the interest in this issue. Boron exposure could cause lung irritation, dermal irritation, genotoxicity in male reproductive system, teratogenicity in concentration-dependent manner. In vitro studies have tried to explain the toxic effects mechanisms. The aim of the current work is to explain the toxic effect mechanisms of boron and boron compounds on body systems.

“…Pb, Cd, and Hg concentrations in human samples (NLF, saliva, and urine) and in Japanese cedar pollen were measured by an ICP-MS (7500cx; Agilent Technologies, Inc, Santa Clara, Calif) using the method previously described. 28,29 Levels of urea in sera and nasal epithelial lining fluid (ELF) are constant regardless of allergic reactions, indicating that urea concentration could be a reliable dilution factor. 3,30 As in our previous studies, 3,22 concentrations of Pb, Cd, and Hg in ELF were adjusted by urea concentrations, according to the following formula: Heavy metal levels in ELF samples 5 Heavy metal levels in NLF 3…”
