This study investigates the presence of microplastics in tap drinking water and evaluates the efficacy of various sorbents for their removal in the context of Kazakhstan’s water treatment system. Water samples taken in the cities of Kokshetau and Krasny Yar (Akmola region) were analyzed. Microplastics were detected in all samples, with concentrations ranging from 2.0 × 10−2 to 6.0 × 10−2 particles/dm3, predominantly in fiber form (74.1%). Outdated technologies and non-compliance with treatment regimens contribute to poor water quality, including high turbidity (87% of samples), color deviations (40% of samples), and acidity issues (20% of samples). To address these challenges, the study examined the sorption efficiency of different sorbents, with results indicating high retention rates (82.7–97.8%) for microplastic particles. Notably, aliphatic structures like PE and PP exhibited higher retention than PET. Among the sorbents tested, the synthesized carbon sorption material (CSM) demonstrated the highest efficiency in both microplastic retention and improvement in water quality parameters, making it a promising option for water treatment facilities and household filters.

This article highlights the technology of processing organic waste in order to obtain biohumus. The varietal composition of urban organic waste has been studied. The technology of preparation of raw materials for obtaining a high-quality substrate for further processing, which provides for the purification of the total mass of organic waste from particles of plastic, glass metal, etc., is considered. An experiment was carried out to determine the optimal composition of the substrate for «California» worms (E. Andrei), which have a high productivity. The optimal parameters of humidity and ambient temperature for the vital activity of worms are considered. In the experiment, three experimental groups were formed, which differed in the composition of organic waste. All three groups contained 40% food waste; 10% – branches, wood cuttings, grass; 10% – tea bags, coffee waste, paper and cardboard; 10% soil and 30% animal waste. In each group, animal waste was different: cattle manure, bird droppings and horse manure. The effectiveness of the varietal composition of the substrate was assessed by the increase in the productivity of «California» worms. The highest results were shown by the substrate in which cattle manure was introduced, the growth of worms in which increased by 6.5 times, the lowest results were in a mixture with the addition of bird droppings – by 5.1.

В статье приведены результаты селекционной оценки и отбору перспективного исходного материала для селекции высокозимостойких форм растений донника. Экспериментальные исследования проводились (2015-2024 гг.) на опытных стационарах Кокшетауского опытнопроизводственного хозяйства, которое находится в с. Шагалалы, Акмолинской области. По результатам исследований, все образцы донника в количестве 637 номеров из мировой коллекции ВИР, местные популяции и селекционные линии в зависимости от степени перезимовки разбиты на 5 групп и определены пределы изменчивости данного признака от 50 до 100 % перезимовки. Очень высокую зимостойкость имели 89 образцов донника, сформировавшиеся в суровых по перезимовке условиях таких экологических условиях, как Западная и Восточная Сибирь (Медет, Обский гигант, Сибирский, Новосибирский, Сретенский 1, Керчинский 1, Саянский, Катэк, Омский скороспелый, Северный, Немюганский и др.); Северный Казахстан (Шедевр 75, Шавекен, Акбас, Сарбас, Кокшетауский, Северо-Казахстанский 7 и др.); Северная Европа (К-32334, К-32335) и Северная Америка (Арктик, К-38852, К-38855). Признак зимостойкости в пределах групп и популяций варьирует слабо. Коэффициент изменчивости (V) не превышает 6,0-8,4%, то есть селекционный отбор может быть весьма эффективным. На основании данной гипотезы был разработан и апробирован селекционный способ отбора зимостойких форм растений донника, где в качестве критериев оценки и отбора приняты такие признаки как, продолжительность вегетативного роста в год посева, диаметр корневой шейки и глубина залегания корневой шейки в почве.
