Summary
An improved fuzzy matter-element (IFME) method enhances river water quality assessment by integrating set pair analysis and variable coefficient methods. This approach provides a more scientific and objective evaluation, especially for polluted rivers.
Area of Science:
- Environmental Science
- Water Quality Assessment
- Fuzzy Mathematics
Background:
- Traditional water quality evaluation methods often face challenges with data interpretation and objectivity.
- Assessing river water quality is crucial for environmental management and public health.
Purpose of the Study:
- To propose and validate an improved fuzzy matter-element (IFME) method for scientific and objective river water quality assessment.
- To evaluate the water quality of Caoqiao River using the novel IFME method.
Main Methods:
- Integration of the classical matter-element (ME) method, set pair analysis (SPA), and variable coefficient method (VCM).
- Application of the IFME method to water quality data from five monitor stations along Caoqiao River.
- Determination of river water quality levels using fuzzy closeness degree.
Main Results:
- The IFME method effectively determined river water quality levels.
- Variable coefficient method (VCM) optimized weight determination, reducing workload and mitigating abnormal data effects.
- Set pair analysis (SPA) enabled more scientific and comprehensive utilization of monitored data.
Conclusions:
- The IFME method offers a more scientific and objective approach to river water quality assessment compared to traditional methods.
- The IFME method is particularly suitable for evaluating seriously polluted rivers.
- An integrated approach is essential for accurate river water quality assessment.

In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...

When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...

Matter: Pure Substances and Mixtures
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...

The earliest recorded discussion of the basic structure of matter comes from ancient Greek philosophers. Leucippus and Democritus argued that all matter was composed of small, finite particles that they called atomos, meaning “indivisible.” Later, Aristotle and others came to the conclusion that matter consisted of various combinations of the four “elements” — fire, earth, air, and water — and could be infinitely divided. Interestingly, these philosophers...

Chemistry is the study of matter and the changes it undergoes. Matter is anything that has mass and occupies space. Matter is all around us; the air, water, soil, mountains, even our bodies are all examples of matter. Matter is divided into three states — solid, liquid, and gas — that are commonly found on earth. The fourth state of matter, plasma, occurs naturally in the interiors of stars.

Pure substances consist of only one type of matter. A pure substance can be an element or a compound. An element consists of only one type of atom, while a compound consists of two or more types of atoms held together by a chemical bond.
Elements
Elements are classified as atomic or molecular based on the nature of their basic units. They are unique forms of matter with specific chemical and physical properties that cannot break down into smaller substances by ordinary chemical reactions. There...
