Uncontrolled Dumpsite Activities as a Catalyst for Ecosystem Services Distortion and Biodiversity Loss in the Aluu Precinct of Rivers State

Open Access Journal of Waste Management & Xenobiotics, Год журнала: 2024, Номер 7(1), С. 1 - 9

Опубликована: Янв. 5, 2024

The processes of disposing household and industrial waste have in recent times become a daunting task for managers growing economies like Nigeria. It has so difficult to find suitable site locate receptacles that most choose harness convert derelict mine sites such as borrow pits final dumpsites. Such actions over time caused colossal damage the environment leading other health-related hazards distortions ecosystem addition phenomenal biodiversity loss. This study was designed assess effects dumpsites on services within Aluu Precinct Rivers State. is cross-sectional survey adopted quantitative strategy it aims measure test effect using objective reliable methods. A representative sample airborne bacteria collected at three different points dumpsite High-Volume Air Sampler (HVAS). used plate count method identify quantify from HVAS samples, further deployed descriptive statistics analyse data answer research questions. Findings indicate there concentration microorganisms samples distances dumpsite, result indicates activities negative impact area, almost all except E. coli exceeds safety limits implying high level bioaerosol contamination air near dump site. recommends amongst others constant engagement with local authorities, communities, management agencies ensure effective disposal minimize environmental harm. Establish long-term monitoring programs track recovery. Measure changes species diversity, soil quality, vegetation.

Management of dredged marine sediments in southern France: main keys to large-scale beneficial re-use

Research Square (Research Square), Год журнала: 2023, Номер unknown

Abstract Each year fifty million cubic meters of marine sediments are dredged in France to maintain and develop harbor activities sustain the economy littoral territories. Because anthropogenic around harbours, bottom can contain more or less significant amounts chemical organic pollutants whose behavior during dredging must be addressed order avoid releasing risks for human environment. French regulations come govern management sediments, considering them ‘safe’ possibly dumped at sea ‘contaminated’ needed treated on land as waste. These last years, new constraints pushing towards a land. This is however challenging few channels proposed promote reuse elimination appears economically environmentally unsustainable. study provides an overview technical regulatory aspects related sediment aims identify discuss limits barriers their valorization. Dredged mainly composed particles with heterogeneous grain size, some being known many applications such building materials growing media. However, several reasons have been put forward explain why these not reused when extracted from sediments. Several technical, socio-economic obstacles low demand stimulated by government incentives good framework. National could help streamline standardizing composition tests, removing "waste" status attributed creating regulated market sediment-based products, thus promising economic sector.

Evaluating of the environmental risks of natural water sources in the Alkalaa municipal community area – South Lebanon

Water Science & Technology Water Supply, Год журнала: 2024, Номер 24(3), С. 760 - 772

Опубликована: Фев. 21, 2024

Abstract Water is considered a fundamental factor, and plays role in public health economic growth. Therefore, it should be free of all kinds microorganisms, chemical substances that are dangerous to fauna flora. Insufficient water supply one the issues confronting Middle Eastern countries, Lebanon becomes typical example. This study aims evaluate basic physical, chemical, microbiological properties for eight distinct sites, southeastern Lebanon, identified during coronavirus pandemic, as worst situation hit began. These tests were carried out by World Health Organization (WHO). The results utilized assess level environmental pollution. A comparison was made between obtained with other studies: southwest northwest region Jordan Valley. novelty this stems from fact first shed light on degree pollution lack education conservation prevention unstudied area, compares locally regionally. In addition, indicate impact Coronavirus behavior habitants region.

Mechanisms of Tolerance in Metal-exposed Brown Algae and the Importance of Monitoring Studies: A Review

Ecotoxicology and Environmental contamination, Год журнала: 2024, Номер 18(2), С. 47 - 72

Опубликована: Фев. 24, 2024

Marine habitats are under threat from the continued release of contaminants into waterways, and monitoring becomes crucialto future management decisions regulations to protect these environments. A key aspect this is choiceof a marine species that able cope with pollution, tolerant exhibit more relevant ecological responses.These species-responses called biomarkers tolerance tested using variety measurements reflect exposureto chemicals. brown macroalgae can be found in wide range environments, including those high metalpollution they widely used programs. Mechanisms vital survival group ofmacroalgae polluted habitats, but mechanisms have not yet been reviewed. The aim critical review article isto summarize historical information available regarding metal macroalgae. We studiesabout exposed metals, conducted both experimental conditionsand field. Also, bibliometric analyses identify most investigations, country contributions andgaps knowledge on topic. Results showed principal extracellular described for marinebrown physical exclusion, exudated ligands, metal-binding cell wall. Epiphytic microorganismswere also capable accumulating given metal. Internally, metallothioneins phytochelatins were importantchelators; furthermore, antioxidant responses may increase tolerance. Omics reveal internalmechanisms by Biomarkers occasionally studies, providingadditional complex chemical mixtures Future studies should make use ofthese improve our understanding metal-tolerance strategies.

Peningkatan Partisipasi Masyarakat melalui Penanaman Mangrove dalam Rehabilitasi Pesisir

Jurnal ABDINUS Jurnal Pengabdian Nusantara, Год журнала: 2023, Номер 7(3), С. 623 - 633

Опубликована: Июль 14, 2023

Penanaman mangrove merupakan salah satu upaya untuk rehabilitasi ekosistem pesisir yang rusak. Penelitian ini dilakukan di Negeri Wakal, sebuah desa terletak wilayah Jazirah Leihitu Kabupaten Maluku Tengah. Kegiatan bertujuan merehabilitasi dalam peningkatan partisipasi masyarakat. Metode digunakan adalah melalui ceramah, dan pelatihan penanaman dengan melibatkan masyarakat sekitar sebagai peserta, serta didampingi mahasiswa Pecinta Alam Geografi dosen pembina. Hasil penelitian menunjukkan bahwa kegiatan Wakal berhasil dilaksanakan baik. Selain itu, juga adanya antusias Evaluasi menyatakan lokasi tersebut masih memerlukan banyak bibit agar bisa direhabilitasi, sistem pendampingan kepada diperlukan memelihara telah ditanam.
