Monitoring Chlorophyll A

21.06.2022

What is Chlorophyll A? Chlorophyll is any of several related green pigments found in the mesosomes of cyanobacteria and in the chloroplasts of algae and plants. Its name is derived from the Greek words χλωρός, khloros (“pale green”) and φύλλον, phyllon (“leaf”). Chlorophyll allows plants to absorb energy from light. Two types of Chlorophyll exist in the photosystems of green plants: Chlorophyll A and B. Chlorophyll A is the most common form of Chlorophyll within photosynthetic organisms and, for the most part, gives plants their green color. Chlorophylls absorb light most strongly in the blue portion of the electromagnetic spectrumRead more

Fuel & Water Pollution

07.06.2022

It is against the law to cause pollution and for the last five years, fuels have consistently been among the UK’s top three pollutants. This means that any fuel spill or leak needs serious and imminent attention. Just one litre of oil is enough to contaminate one million litres of water, putting human life, wildlife and vegetation at severe risk. Depending on the density of the oil, it will either float, semi-submerge or sink in river, lake or stream water. The same oil, however, may have a different reaction when in seawater as the salt changes the density of theRead more

Detecting BTEX in Groundwater

07.06.2022

How do BTEX compounds enter groundwater? BTEX can contaminate natural waters through leaks in underground pipes, spills, improper disposal or leaching from landfills. As these chemical compounds are known to cause serious health effects to humans and pose a risk if exposed, a maximum contaminant level of 5 µg/L Benzene was established by the US EPA for drinking water to ensure removal from groundwater and surface water sources. Measurement is also commonly required for industrial manufacturers discharging petroleum contaminated water to municipal wastewater treatment plants. When gasoline is in contact with water, BTEX compounds account for as much as 90%Read more

Chile’s Algal Blooms Challenges

12.05.2022

Once considered a seasonal delicacy, salmon is now one of the most widely available superfoods in western supermarkets. The fatty fish is rich in omega-3 fats, selenium, and several B vitamins, and has been attributed to lowering the risk of illnesses and conditions such as heart attacks and strokes. In Chile, salmon farming has grown to become one of the nation’s top trading exports and the country now produces a quite remarkable 25% of the world’s salmon supply, with more than 1,000 fish farms in operation along the length of the Patagonian coastline. Salmon is Chile’s top export outside ofRead more

Fluorescence Ballast Water Testing: STAF or PAM?

31.01.2022

Fluorescence ballast water testing tools come in two varieties: STAF (Single Turnover Active Fluorometry) and PAM (Multiple Turnover Pulse Amplitude Modulated). In this article, we’re taking a look at some of the key differences that set these two techniques apart, and how these differences impact the results of ballast water compliance testing. Ballast water testing: why? Ballast water is defined as water taken on board a ship to control trim, list, draught, stability or stresses of the ship. Ballast water operations are essential for the safe operation of ships and a perfectly standard part of shipping – ballast water providesRead more

The Science Behind Chelsea Technologies: Excerpts & Updates

Ballast Water Webinar Week

17.01.2022

Chelsea Technologies’ Michael Haraldsson joins the panel this week at Ballast Water Webinar Week to discuss the many issues that are surfacing around commissioning testing. The amendments to regulation E-1 of the BWM Convention adopted by MECP 74 require biological efficacy testing when commissioning a BWTS on board a vessel. But what happens if the commissioning test is unsuccessful? Beginning Tuesday 18 January, Ballast Water Webinar Week will be holding a series of webinars focused on deadlines, commissioning tests and shipowner requirements for 2022 and 2023. Each webinar is meticulously researched and speaks to a key industry challenge, headache or opportunity.Read more

UN Global Goal 3 & The Tryptophan Breakthrough

10.01.2022

What is UN Sustainable Development Goal 3? In the fine words of the UN declaration, ‘By 2030, substantially reduce the number of deaths and illnesses from hazardous chemicals and air, water and soil pollution and contamination.’ Inadequate and unsafe drinking water, sanitation and hygiene is linked to 60 per cent of the disease burden from diarrhoea. UN Goal 3 is one of 17 Sustainable Development Goals established by the United Nations General Assembly in 2015. UN Global Goal 3 (SDG 3 or Global Goal 3) concerns itself with basic human health. Tragically, the world is falling short on its promiseRead more
