Capillaries that surround the proximal convoluted tubules are

Peritubular capillaries.

Explanation:

Proximal convoluted tubules plays an important role in the process of urine formation. This tubule is present between the convoluted parts of loop of henle and bowman's capsule.

Peritubular capillaries are the small blood vessels that are mainly supplied by efferent arterioles. These capillaries help in the secretion and reabsorption between the blood and the lumen of the nephron. Peritubular capillaries are surrounded in the  proximal convoluted tubules.

Thus, the answer is peritubular capillaries.

significant amounts of nitrogen oxides, carbon monoxide, and other pollution

explanation:

passenger vehicles are a major pollution contributor, producing significant amounts of nitrogen oxides, carbon monoxide, and other pollution. in 2013, transportation contributed more than half of the carbon monoxide and nitrogen oxides, and almost a quarter of the hydrocarbons emitted into our air.

the oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf, but operationally is often referred to as beginning where the water depths drop to below 100 meters (328 feet), seaward from the coast to the open ocean.
