Health Effects of Cyanogen Chloride and Methods of Controlling its Percentages in Water

REEM N. DABAIBEH

European Journal of Molecular & Clinical Medicine, 2021, Volume 8, Issue 3, Pages 2988-3004

Cyanogen chloride is a toxic chemical compound with the formula NCCl. This linear,
triatomic pseudo-halogen is an easily condensed colorless gas. More commonly
encountered in the laboratory is the related compound cyanogen bromide, a
room-temperature solid that is widely used in biochemical analysis and preparation.
This paper presents a description for Cyanogen chloride formation and creations, its
effects on animals and human bodies, and finally methods to control its percentages
in drinking water under the acceptable levels. The method of controlling its
concentration in water is summarized by using suitable chemical additives and noting
the time for settlement and then removed from the samples. A comparison between 4
additives in removing Cyanogen chloride is performed for the same sample of water.
It is found that as the concentration of NCCl increases the pOH of the sample
increases while pH decreases. Also, for the four additives NH4+, CN-1, Cl2 and
SO2 for the water samples, it was found that SO2 is the most efficient chemical
additive in removing CNCl since it needs the lowest time of removing CNCl.

Abstract. The article presents the materials of experimental research on the new defoliant of
cotton "Phosphodef". By parameters of acute toxicity the studied preparation belongs to low
hazardous compounds, IV class of hazard. The irritating effect of the preparations on mucous
membranes of eyes and skin; cumulative properties of the preparation have been studied in
acute experiments. Hygienic standards of the preparation in air, water, soil and food products;
sanitary protection zones, terms of employment are scientifically proved. According to the
research results, the use of defoliant "Phosphodeph" in agriculture from hygienic positions is
not objectionable.

Lead and its compounds are continuously detected in environmental objects at
various concentrations and doses. Lead is a general plasma poison that affects the nervous,
bone, endocrine system, blood and blood vessels, parenchymatous organs, gastrointestinal
tract, metabolism, reproductive function, immune status and resistance. In this regard, there
is an acute need to study in the experiment features of the response of the body of rats at
the same time aerogenic and oral intake of lead and the development of its permissible
values in the air, water and food products, taking into account the complex effects.
Objective: to determine experimentally the peculiarities of biological response of
experimental animals at simultaneous aerogenic complex intake of lead and development
of its permissible values in air, water and food products.
Methods: Concentration (dose) - time-effect relationship was used. For inhalation,
200-liter chambers were used in the experiment, proposed by B.A. Kurlyandsky. Modern
highly sensitive biochemical, physiological, gonad and embryotoxic indicators were used
to assess the resorptive toxic effect of lead.

The article analyzes the state of water use in agriculture in Uzbekistan and examines the reasons for their waste. It analyzes the current state of water use on irrigated agricultural lands in the world and in the country, as well as programs of measures to address issues and problems of efficient use, and makes relevant proposals for their more efficient use. It also analyzes the views of experts on the recognition of water efficiency indicators in relation to key indicators, based on the fact that the same indicators cannot be applied uniformly as a result of global climate change, given the characteristics of specific and relative indicators of water use efficiency. In Namangan region, econometric models of changes in the volume of production depending on the conditions of water use in arable lands were developed and analyzed. As an indicator of water efficiency, crop yields were studied and suggestions and recommendations for water efficiency were presented.

European Journal of Molecular & Clinical Medicine, 2020, Volume 7, Issue 3, Pages 2775-2780

UzPITI-201 cotton variety seeds were sown under a transparent film on March 15-25, 155, 4 thousand seedlings per hectare were left and mineral fertilizers were applied at N180Р125К90 kg/ha rate and also in the variant irrigated in the optimal 70-75-60% order compared to LFMC, i.e. due to the soil conditions formed under the positive influence of the transparent film, the highest yield was 41,4 ts/ha, an increase in the cotton fiber technological quality was observed, along with the additional cotton yield cultivation of 5, 6-9,3 s per hectare compared to the control options planted in seeds double row and single row in the usual open method
