Environmental Impacts of Boating Pollutants

  

(Unless otherwise stated, material is from Connell and Miller 1984) Pollutant	Sources and Characteristics	Environmental Activity	Environmental or Human Health Effects
Detergents	 Most cleaning agents, detergents and soaps  Oil spill dispersants 29  Breaks down oils and greases on boats	 Accumulates in sediments  Broken down by microorganisms	 Toxic to marine plants and animals  Impairs breathing in fish 18  Reduces amounts of oxygen in affected waters  Produces unsightly foam on the water surface
Marine debris	 Commercial and recreational boating 11  Plastics, food wastes, packaging, lines, nets, fish cleaning wastes 3  Plastics degrade very slowly  Some wastes become nutrients (see "Nutrients")		 Can choke / strangle sea animals 3, 11  Ghosts nets, and traps endanger divers 3  Can transport harmful non native species 11  Snagged by props and engines 3  Ruins recreational beaches 11
Acidic & Alkalis Substances	 Battery acid, lye and other strong acids or bases in vessel cleaning products 13  Dissolves easily in water	 Increases natural acidity or alkalinity of water by decreasing or increasing pH respectively	 Toxic to marine plants and animals  Increases the toxicity of other toxic substances, metals, other pollutants and chemicals  Can irritate or damage skin
Metals	 Paint particles from hydro washing, metal shavings from engine wear, and consumer products containing metals  Dissolves according to water conditions	 Accumulates in sediments, marine plants, and animals  Persistent in the environment  Some metals broken down by microorganisms	 Toxic to marine plants and animals  Changes the food web in the marine environment by eliminating certain species
Copper (Cu)	 Used as a toxic agent in antifouling paints  Dissolves according to water conditions	 Accumulates in sediments, marine plants, and animals  Persistent in the environment	 Very toxic to fish when combined with zinc sulfates 16  Long term toxicity to marine plants and animals
Tributlytin (TBT)	 Still used as a toxic agent in antifouling paint on aluminum hulls, outboard motors & lower drive units 4, 16	 Accumulates in sediments, marine plants, and animals 16  Persistent in the environment	 Toxic even in small amounts to marine plants and animals, especially bottom feeders 16  TBT contaminated shellfish are dangerous to

Zinc (Zn)	 Anticorrosive zincs and paint pigments  Dissolves according to water conditions, which can make Zn more available to marine organisms 16	 Persistent in the environment	 Toxic to marine plants and animals, even small amounts 15
Oil / Fuel	 Normal boat operation, fueling, engine maintenance, spills, runoff, and bilge discharge  Dissolves slowly in water, clings to particles and sediments in marine environments	 Broken down by sediment microorganisms22  Accumulates in sediments, marine plants, and animals  High accumulation in estuaries and intertidal areas	 Some components toxic to marine plants and animals even at low concentrations 24  Some components cause cancer, mutations and / or birth defects  Behavioral changes in shellfish and fish 24  Discoloring and bad taste in flesh of fish 20, 25, 26
Dusts and sediments	 Vessel scraping and sanding, erosion during construction and urban runoff  Heavy metals, nutrients, hydrocarbons, etc. adhere to dusts and sediments	 Sediment bound contaminants released to water if disturbed	 General lowering of water quality  Burial of habitat, food and / or organisms
Nutrients	 Runoff, sewage, erosion, garbage & detergents containing (P)hosphorous or (N)itrogen	 Used by marine plants and organisms for food (P,N)  Accumulates in sediment (P)	 Increase in algae growth which decreases light and oxygen in the water (eutrophication)  (N) can be toxic in higher concentrations
Solvents	 Vessel maintenance & repair activities  Paints, varnishes, paint removers and lacquers as well as degreasing agents  Does not dissolve in water 13	 Sink in water until they reach an impervious surface  Acetone lingers in air and is transported to sediment & water	 Large amounts can cause dizziness, disorientation and unconsciousness in the user 2
Anti-freeze	 Used as engine coolant and freeze prevention during winter storage  Improper use & storage creates leaks or spills 13	 Fate similar to solvents 13	 Ethylene glycol is deadly to humans, pets & marine organisms in low doses 2  Propylene glycol (orange/pink color) is less toxic than ethylene glycol (blue/green color) and is preferred for use in boats 7

The US trade association has sold the Los Angeles Boat Show and San Diego International Boat Show to Duncan McIntosh Company

 

NMMA makes strategic changes to its boat show roster           

NMMA, as part of strategic changes to its boat show roster, has reached an agreement to transfer ownership of the Los Angeles Boat Show and San Diego International Boat Show to Duncan McIntosh Company, Inc., effective immediately.

The 2016 Los Angeles Boat Show completed a successful four-day run on February 28 with an eleven percent increase in attendance, helping kick off the transfer on a positive note. As for the 2016 San Diego International Boat Show, set to run June 16-19 at the Sheraton Hotel & Marina on Harbor Island, it is business as usual and all existing agreements for 2016 will be honored by Duncan McIntosh Company. For exhibitors who have already contracted for space, NMMA has assigned space contracts and deposits to Duncan McIntosh Company. All exhibitor questions related to the Los Angeles and San Diego shows should be directed to Janette Hood at the Duncan McIntosh Company.

Additionally, following the cancellation of the San Francisco Boat Show in January due to weather and given challenges in finding a suitable long-term home for the show in Northern California, NMMA will not be producing a San Francisco show in 2017. NMMA President Thom Dammrich notes, “It was not an easy decision to make but after listening to our exhibitors and exploring our options for alternative host sites, it became clear we would not be able to produce the kind of event our attendees and exhibitors have come to expect from NMMA. We thank our exhibitors for their support as we looked to use this show as a way to reinvigorate the Northern California market and hope our exhibitors understand our reasons behind this difficult decision.”

With these changes come changes at NMMA. Without these shows on its roster, the NMMA West offices will be closing later this Spring. In a letter to exhibitors, Dammrich noted, “We are sad to say goodbye to Dave Geoffroy and his talented team of professionals and thank them for their hard work and dedication in working with us to grow recreational boating in California. Dave has been a fixture in the Southern California boating industry for forty-five years and has served the industry as an association leader for eighteen years. We hope you will join us in wishing them well in their future endeavors.”

While the NMMA West offices are closing and shows are transitioning, NMMA will continue serving the needs of the marine industry on the West Coast. David Dickerson and NMMA’s state government relations team will remain active in all California legislative and regulatory efforts. What's more, John McKnight's work with CARB and Nicole Vasilaros' work in ensuring California is part of our federal government relations efforts will continue, uninterrupted. Additionally, the NMMA teams supporting statistics, certification, marketing and PR in California are moving full speed ahead. California remains a key region that's integral to the success of the entire U.S. boating industry and a priority for NMMA.
