تلوّث المياه في العراق: أزمة خفية تحت سطح النهر

في بلدٍ وُلِدَ على ضفاف دجلة والفرات، تبدو مفارقة تلوّث المياه مأساة مزدوجة: مائيّة وهُويّاتية. فالعراق الذي علّم البشرية نظم الري والزراعة، أصبح اليوم يواجه واحدة من أخطر أزمات تلوث المياه في الشرق الأوسط، حيث تختلط ملوحة شط العرب بنفايات المستشفيات، وتتقاطع قنوات الري مع مجاري الصرف الصحي، في مشهد يعكس عمق الخلل البيئي والسياسي والإداري. أولًا: مصادر التلوث المائي في العراق رغم أن الصورة العامة تشير إلى “شح المياه”، إلا أن نوعية المياه تمثل تهديدًا أكبر، وأكثر خفاءً. مياه الصرف الصحي غير المعالجة أكثر من 70% من مياه الصرف الصحي في العراق تُصرّف مباشرة في الأنهار دون معالجة، وفق … Continue reading

The Retreat of the Tigris River and Its Impact on Biodiversity in Northern Iraq

The Tigris River, one of Mesopotamia’s twin lifelines, plays a vital ecological and socioeconomic role in northern Iraq. However, over the past two decades, it has undergone significant hydrological decline. This retreat, driven by a combination of climate change, upstream damming, and poor water governance, has caused a cascading effect on ecosystems and livelihoods, particularly in the northern provinces of Iraq such as Nineveh, Dohuk, and parts of Erbil. The drop in water levels in the Tigris River has: Severely impacted agricultural lands, especially in riparian zones that once depended on natural flooding cycles for soil fertility Diminished fish populations … Continue reading

Bioremediation: Fighting Pollution with Bacterial Assistance

Bioremediation is an engineering process which uses microorganisms to degrade a material. It can be used to treat contaminated media such as water, air and soil, by altering the environmental conditions to stimulate growth of microorganisms and degrade the target pollutant and enhance the quality of the media. In this age of rapid industrialization and depleting natural resources, there is an alarming need for a much effective sustainable development model and new ways to decontaminate and re-energize our surrounding land, water and air. Bioremediation provides an efficient and environment-friendly treatment system compared to various other remediation technologies involving chemicals and … Continue reading

Why PFAS Removal Solutions Are Essential for Environmental Protection: 5 Key Reasons

The Environmental Impacts of Seawater Desalination

Desalination is a process that removes salt and minerals from seawater and turns it into a potable resource. It is extremely helpful in areas experiencing rising water demands due to water scarcity, droughts, growing populations and increased water consumption. With the ocean covering most of the Earth’s surface, seawater provides a sustainable, long-term solution to a problem that won’t soon dissipate. By 2015, 18,000 desalination plants had cropped up worldwide, producing 22,870 million gallons of fresh water per day. Experts believe desalination, coupled with future advancements in technology, could be the key to establishing drought-proof communities worldwide. A clean source … Continue reading

10 Ways To Improve Indoor Air Quality

Indoor air pollution is considered as one of the top environmental risks to public health worldwide due to increasing number of building-related illnesses. Studies have found that concentration of indoor pollutants is significantly higher indoors than they are in outdoor environment, which is two to five times and sometimes hundred times higher than outdoor levels. As most of the people spend 80% to 90% of their lives indoor, indoor air quality has significant implication on sustainability. Impact of Poor Indoor Air Quality Decreased indoor air quality can affect quality of life of the building occupant, increase health risks and increase … Continue reading

The Promise of Bioremediation

Ecosystems are permanently challenged with the abundant release of toxic compounds into the environment due to a wide range of anthropogenic activities. Apparently, contamination with oil spills and oily waste disposal are a major global concern since it’s extensively damaging the biodiversity, threatening the public health and has severe ecological and socioeconomic consequences. For example, in 1989, thousands metric tons of crude oil spill in Alaska, led to a massive loss in the marine life as well as several long-term environmental impact. Minor oil spills and non-point oil contamination are no less threats to public health, biodiversity and environment. Awareness … Continue reading

Hazardous Waste Management in Qatar: Progress and Challenges

A country with an abundance of raw materials, cheap labor, and a rising demand for energy, Qatar needed to diversify its industrial sector in the 1970s. From then onwards, the use of fertilizers, petrochemicals, and gas liquefaction plants have grown exponentially. The magnitude of hazardous waste and the pollution to be produced from different streams have not been thoroughly considered, but Qatar has taken serious steps to implement commitments for sustainable development by passing laws and treaties, such as law No.4 in 1981 issuing safeguards and providing requirements for the protection of the environment, and by signing onto treaties such … Continue reading
