Questions: Math the pollutants with effects or other significant aspects A. Salinity B. Alkalinity C. Acidity D. Nitrate 1. Excessive productivity 2. Cake enter from pyrite or from the atmosphere 3. Osmotic effects on organisms 4. From soils and mineral strata

The task is to match each pollutant with its corresponding effect or significant aspect. Let's analyze each option:

A. Salinity

• 3. Osmotic effects on organisms: Salinity refers to the concentration of salts in water or soil. High salinity can cause osmotic stress in organisms, affecting their ability to absorb water and nutrients.

B. Alkalinity

• 4. From soils and mineral strata: Alkalinity is often derived from the presence of carbonate, bicarbonate, and hydroxide ions, which can originate from soils and mineral strata.

C. Acidity

• 2. Cake enter from pyrite or from the atmosphere: Acidity in water bodies can result from acid rain, which is caused by atmospheric pollutants like sulfur dioxide and nitrogen oxides. These can originate from pyrite oxidation or atmospheric deposition.

D. Nitrate

• 1. Excessive productivity: Nitrates are nutrients that can lead to eutrophication, causing excessive productivity in aquatic ecosystems, often resulting in algal blooms.

In summary, the correct matches are:

• A. Salinity: 3. Osmotic effects on organisms
• B. Alkalinity: 4. From soils and mineral strata
• C. Acidity: 2. Cake enter from pyrite or from the atmosphere
• D. Nitrate: 1. Excessive productivity
