Mulching as a Sustainable Water and Soil Saving Practice in Agriculture: A Review

Agronomy, Год журнала: 2022, Номер 12(8), С. 1881 - 1881

Опубликована: Авг. 10, 2022

This research was carried out in order to demonstrate that mulching the ground helps conserve water, because agricultural sustainability dryland contexts is threatened by drought, heat stress, and injudicious use of scarce water during cropping season minimizing surface evaporation. Improving soil moisture conservation an ongoing priority crop outputs where resources are restricted controlled. One reasons for desire less agriculture rising demand brought on world’s growing population. In this study, organic or biodegradable mulches dominated materials, while inorganic mostly comprised plastic-based components. Plastic film, straw, gravel, volcanic ash, rock pieces, sand, concrete, paper pellets, livestock manures among materials put surface. Mulching has several essential applications, including reducing loss erosion, enriching fauna, improving properties nutrient cycling soil. It also reduces pH soil, which improves availability. deterioration limiting runoff loss, it increases availability evaporation, managing temperature, irrigation requirements. review extensively discusses benefits synthetic production, as well uses conservation. As a result, very important farmers choose rather than applications.

Assessing the Release of Microplastics and Nanoplastics from Plastic Containers and Reusable Food Pouches: Implications for Human Health

Environmental Science & Technology, Год журнала: 2023, Номер 57(26), С. 9782 - 9792

Опубликована: Июнь 21, 2023

This study investigated the release of microplastics and nanoplastics from plastic containers reusable food pouches under different usage scenarios, using DI water 3% acetic acid as simulants for aqueous foods acidic foods. The results indicated that microwave heating caused highest into compared to other such refrigeration or room-temperature storage. It was found some could many 4.22 million microplastic 2.11 billion nanoplastic particles only one square centimeter area within 3 min heating. Refrigeration storage over six months can also millions billions nanoplastics. Additionally, polyethylene-based pouch released more than polypropylene-based containers. Exposure modeling suggested estimated daily intake 20.3 ng/kg·day infants drinking microwaved 22.1 toddlers consuming dairy products polypropylene Furthermore, an in vitro conducted assess cell viability showed extracted container cause death 76.70 77.18% human embryonic kidney cells (HEK293T) at 1000 μg/mL concentration after exposure 48 72 h, respectively.

State-of-the-art review on photocatalysis for efficient wastewater treatment: Attractive approach in photocatalyst design and parameters affecting the photocatalytic degradation

Catalysis Communications, Год журнала: 2023, Номер 183, С. 106764 - 106764

Опубликована: Сен. 15, 2023

This review focuses on recently proposed photocatalyst designs for maximizing the efficiency of photogenerated charge carriers to improve photocatalytic performance photocatalysts. These include doping with metal and non-metal ions, surface grafting, noble deposition, dye sensitization, heterostructure fabrication. In addition, this thoroughly examines all prominent parameters that can influence degradation Furthermore, summarizes energy-band structures photocatalysts are suitable both O2 reduction oxidation H2O molecules generate reactive oxygen species. Lastly, we discuss future trends in development environmental applications.

Food and human safety: the impact of microplastics

Critical Reviews in Food Science and Nutrition, Год журнала: 2022, Номер 64(11), С. 3502 - 3521

Опубликована: Окт. 17, 2022

Plastic waste pollution is one of the biggest problems in world today. The amount plastic environment continues to increase, and human exposure microplastic (MP) has become a reality. This subject attracted attention whole world. MP problem also been noticed by scientific community. term mostly used define synthetic material with high polymer content that can have size range from 0.1 5000 µm. paper aims characterize routes MP, its sources, identify food types contaminated plastics. review addresses current state knowledge on this type particles, particular emphasis their influence health. Adverse effects depend sources exposure. most common route believed be gastrointestinal tract. Sources include fish, shellfish, water as well tea, beer, wine, energy drinks, soft milk, salt, sugar, honey, poultry meat, fruits, vegetables. Studies shown particles PET, PE, PP, PS, PVC, PA, PC are frequently found food.

Bioplastics for Food Packaging: Environmental Impact, Trends and Regulatory Aspects

Foods, Год журнала: 2022, Номер 11(19), С. 3087 - 3087

Опубликована: Окт. 5, 2022

The demand to develop and produce eco-friendly alternatives for food packaging is increasing. huge negative impact that the disposal of so-called “single-use plastics” has on environment propelling market search new solutions, requires initiatives drive faster responses from scientific community, industry, governmental bodies adoption implementation materials. Bioplastics are an alternative group materials partly or entirely produced renewable sources. Some bioplastics biodegradable even compostable under right conditions. This review presents different properties these materials, mechanisms biodegradation, their environmental impact, but also a holistic overview most important available in potential application packaging, consumer perception bioplastics, regulatory aspects, future challenges.

Microplastics, defined as particles <5 mm in diameter, are emerging environmental pollutants that pose a threat to ecosystems and human health. Biofilm degradation of microplastics may be an ecologically friendly approach. This review systematically summarises the factors affecting biofilm proposes feasible methods improve efficiency microplastic degradation. Environmentally insensitive microorganisms were screened, optimized, commercially cultured facilitate practical application this technology. For strain screening, technology should focus on microorganisms/strains can modify hydrophobicity microplastics, degrade crystalline zone metabolise additives microplastics. The biodegradation mechanism is also described; secreting extracellular oxidases hydrolases key for Measuring changes molecular weight distribution (MWD) enables better analysis behaviour has relatively few applications because its low efficiency; however, enrichment freshwater environments wastewater treatment plant tailwater currently most effective method treating with biofilms.
