Run For The River

Theme: Run For The River

Date: May 23, 2026

Organised:  CBEES & BCFRC

Event Coordinator: Dr. Md Muzammel Hossain

Run through a "water" obstacle, such as a series of foam blocks or a shallow water pit, to simulate the river's role as a habitat for aquatic life.

Run along a "riverbank" or a designated path lined with trees or other vegetation to represent the river's ecosystem.

Run through a simulated "cityscape" or a busy area to highlight the importance of rivers for human needs, such as water supply and transportation.

Run through a "polluted" area, marked by obstacles or challenges such as "oil slicks" or "chemical spills," to raise awareness about the environmental impact of human activities on rivers.

Run uphill or on uneven terrain to replicate the river's course through mountains, canyons, and valleys.

Run up a small hill or incline to simulate the melting of glaciers, which is a primary source of many rivers.

Virtual run is a flexible, non-competitive running event that participants can complete at their own convenience and location within a specified time frame. It allows individuals to run, walk, or jog anywhere—such as parks, trails, treadmill, or streets—while still participating in a collective event. Jog or walk along a winding path, symbolizing the meandering journey of a river from its source.

Exposure Science Research : AGU25

Dr. Md Muzammel Hossain successfully participated in AGU25 by presenting a poster at this international conference held virtually. The poster was titled "Urban Ornamental Plant Studies: Remarks on Exposure Science and Public Health Risk Concerns." AGU25 took place at the New Orleans Ernest N. Morial Convention Center in New Orleans, LA, USA, from December 15 to 19, 2025. Vice President Vicki Hawarden confirmed his participation with a certificate of attendance.

Consumers should also be aware of the sources of betel leaves

 Piper betel, commonly known as betel leaf, is widely used in many cultures for chewing, medicinal purposes, and religious rituals. While it offers various social and traditional benefits, there is growing concern about the possible health risks associated with heavy metal contamination in betel leaves. Heavy metals such as lead (Pb), arsenic (As), cadmium (Cd), and mercury (Hg) can contaminate Piper betel through environmental factors like polluted soil, water, and air. When contaminated betel leaves are consumed regularly, these toxic metals can bioaccumulate in the human body, leading to serious health issues. Mentor Dr. Md Muzammel Hossain is actively raising awareness about the ongoing environmental and health issues associated with Piper betel.

The possible health risks of heavy metals in Piper betel include neurological impairments, especially in children and pregnant women, due to lead and mercury exposure. Chronic ingestion of arsenic-contaminated betel leaves can cause skin lesions, cancers, and cardiovascular problems. Cadmium exposure may result in kidney damage and bone demineralization. Additionally, heavy metals can interfere with cellular functions and immune responses, increasing vulnerability to diseases.

Given these potential risks, it is essential to monitor and regulate the levels of heavy metals in Piper betel and promote safe cultivation practices. Consumers should also be aware of the sources of betel leaves and prioritize those cultivated in uncontaminated environments to minimize health hazards associated with heavy metal exposure.
