pollution is the contamination of air, water or soil materials interferes with human health.
Pollution
a graduated cylinder
The major disadvantage of using synthetic material is that they are non bio degradable . Thus they cause pollution like soil pollution and water pollution.
100mL of measuring cylinder is the most appropriate (more than beaker) piece of equipment to measure 85mL of water.
Glass Graduated Cylinders
It isn't! Your equipment is just not sensitive enough to measure it.
pH does not "get into your water"- it is a measure of what the water IS- acid or alkaline. Materials that make the water acidic or alkaline can enter the water many ways- from pollution that is washed out of the air when it rains, by pollutants that go directly to surface waters, etc. But nature also plays a role. Water that seeps through limestone rock becomes alkaline from the limestone. Water that seeps through plant materials (humus or peat) becomes acidic, since the plant materials are mildly acidic.
pollution leaks out into the water and makes water pollution
warm water causes proteins in organic materials to coagulate and stick.

A graduated cylinder would be the best piece of laboratory equipment to measure a 350 ml of water. It is designed with volume markings and is specifically used for accurate measurements of liquids.
