 Suốt nhiều năm, người dân xả thải bừa bãi ra bờ biển làm bãi cát đẹp trở thành nơi chứa rác thải, ô nhiễm nghiêm trọng.

Trên bãi biển ô nhiễm, những đứa trẻ ở thị trấn Phan Rí Cửa (huyện Tuy Phong, Bình Thuận) dùng rác làm đồ chơi, chạy nhảy trên cát đầy rẫy túi nylon và mảnh sành, thủy tinh.

‘Khủng khiếp’, bình quân mỗi người Việt tiêu thụ 0,9-1kg thuốc BVTV/năm

Thuốc độc ở chính trong ta:

NN – 27/07/2018, 08:42 (GMT+7) Hiện có khoảng 200 doanh nghiệp tham gia sản xuất kinh doanh thuốc BVTV, khoảng 100 nhà máy sản xuất thuốc BVTV và hơn 30 ngàn đại lý buôn bán thuốc BVTV. Đáng chú ý là thực sự chỉ khoảng 15-20 doanh nghiệp chi phối...

Theo ông Trương Quốc Tùng – nguyên Phó Chủ tịch Thường trực Hội Khoa học Kỹ thuật Bảo vệ Thực vật (BVTV) Việt Nam, lịch sử dùng thuốc BVTV ở nước ta được bắt đầu ở miền Bắc vào năm 1955. Nó tỏ ra là phương tiện quyết định, nhanh chóng dập tắt các dịch sâu bệnh trên diện rộng. Nếu không có thuốc BVTV nhiều dịch hại cây trồng có thể làm giảm 40-60% năng suất trên diện rộng, cục bộ có thể mất trắng.

10 Rivers Contribute Most of the Plastic in the Oceans

ScientificAmerica

The 10 rivers that carry 93 percent of that trash are the Yangtze, Yellow, Hai, Pearl, Amur, Mekong, Indus and Ganges Delta in Asia, and the Niger and Nile in Africa. The Yangtze alone dumps up to an estimated 1.5 million metric tons of plastic waste into the Yellow Sea.

Our seas are choking on plastic. A staggering eight million metric tons wind up in oceans every year, and unraveling exactly how it gets there is critical. A recent study estimates that more than a quarter of all that waste could be pouring in from just 10 rivers, eight of them in Asia.

“Rivers carry trash over long distances and connect nearly all land surfaces with the oceans,” making them a major battleground in the fight against sea pollution, explains Christian Schmidt, a hydrogeologist at the Helmholtz Center for Environmental Research in Leipzig, Germany.

The Challenge of Agricultural Pollution : Evidence from China, Vietnam, and the Philippines

Thumbnail
In emerging East Asia, agricultural output has expanded dramatically over recent decades, primarily as a result of successful efforts to stimulate yield growth. This achievement has increased the availability of food and raw materials in the region, drastically diminished hunger, and more generally provided solid ground for economic development. The intensification of agriculture that has made this possible, however, has also led to serious pollution problems that have adversely affected human and ecosystem health, as well as the productivity of agriculture itself. In the region that currently owes the largest proportion of deaths to the environment, agriculture is often portrayed as a victim of industrial and urban pollution, and this is indeed the case. Yet agriculture is taking a growing toll on economic resources and sometimes becoming a victim of its own success. In parts of China, Vietnam, and the Philippines—the countries studied in The Challenge of Agricultural Pollution—this pattern of highly productive yet highly polluting agriculture has been unfolding with consequences that remain poorly understood. With large numbers of pollutants and sources, agricultural pollution is often undetected and unmeasured. When assessments do occur, they tend to take place within technical silos, and so the different ecological and socioeconomic risks are seldom considered as a whole, while some escape study entirely. However, when agricultural pollution is considered in its entirety, both the significance of its impacts and the relative neglect of them become clear. Meanwhile, growing recognition that a “pollute now, treat later” approach is unsustainable—from both a human health and an agroindustry perspective—has led public and private sector actors to seek solutions to this problem. Yet public intervention has tended to be more reactive than preventive and often inadequate in scale. In some instances, the implementation of sound pollution control programs has also been confronted with incentive structures that do not rank environmental outcomes prominently. Significant potential does exist, however, to reduce the footprint of farms through existing technical solutions, and with adequate and well-crafted government support, its realization is well within reach.

A University of Montana researcher and her collaborators have published a new study that reveals increased risks for Alzheimer’s and suicide among children and young adults living in polluted megacities.

Dr. Lilian Calderón-Garcidueñas said her group studied 203 autopsies of Mexico City residents ranging in age from 11 months to 40 years. Metropolitan Mexico City is home to 24 million people exposed daily to concentrations of fine particulate matter and ozone above U.S. Environmental Protection Agency standards. The researchers tracked two abnormal proteins that indicate development of Alzheimer’s, and they detected the early stages of the disease in babies less than a year old.

Locals say the company has been trying to cover up the evidence and switched to operating at night following complaints.

A petroleum company has been caught red-handed dumping untreated waste in a protected forest on the outskirts of Hanoi.

Residents of Soc Son District started noticing lines of trucks queuing up to dump tons of waste shortly before the Lunar New Year (Tet).

Viet Nam News HÀ NỘI — The Nhuệ-Đáy river basin continues to suffer from pollution despite a range of environmental protection projects that have been carried out by several agencies, including Hà Nội’s Department of Natural Resources and Environment. 

Lê Tuấn Định, deputy head of the department, said the level of pollution in the water had steadily worsened and that many stretches of the river were seriously polluted, especially during the dry season.

He said, the water quality in the Nhuệ and Đáy rivers would improve when they received water from the Hồng (Red) River.

However, statistics from the department show that the water level of the Hồng River has been low since 2003. Tiếp tục đọc “Nhuệ-Đáy river basin polluted despite clean-up efforts”

The trend is set to continue, with volumes of e-waste expected to rise to 52.2 million metric tonnes by 2021. Tiếp tục đọc “Forty per cent of global e-waste comes from Asia”

Plankton decline hits marine food chain

DW_Plankton is the basis for the entire marine food web – and it is under threat. From the Mediterranean to the Pacific, animals have been struggling to survive, due apparently to changes with plankton.

Food chains represent the greatest interdependency within the webs of life. The marine food chain, for instance, is essential for oceans – and depends on plankton. But environmental changes and human activities may be threatening plankton– and therefore all marine animals.

According to a recent study,the biomass of sardines and anchovies has been decreasing at alarming rates in the Mediterranean Sea. At the same time, sea lions are struggling to forage on the coasts of California. Both cases have shed light on how a single food chain element can affect all others.

While it is still unknown whether species will be able to adapt to new conditions, the marine food chain is already experiencing drastic changes – and plankton plays a crucial role across the board.

“If anything happens to the plankton, an immediate cascade effect will take place on the food chain,” Ivan Nagelkerken, a University of Adelaide’s biology professor, told DW.

Building blocks of life

Plankton are tiny aquatic organisms that drift through the sea, forming the basis of the marine food chain.

For plankton, both quantity and quality – in terms of nutrients – affect life up the food chain. Tiếp tục đọc “Plankton decline hits marine food chain”
